Gauss, Wisp, or Titania, Mesa?

Of those 4, I use Wisp by far the most. Titania and Gauss are both faster, but not by an earth shattering amount. I feel that Wisp is overall more useful when speed isn't the main thing you're after, as well. Health/heath regen and haste buffs are always useful, and the shock mote can usually be useful.

Wisp and Gauss won't necessarily be quick to acquire via playing and drops, though (can always buy with plat, but I'd recommend not doing that).

Wisp is also who I'd say is the best solo frame out of all of those, simply due to the buffs. But any frame can be built to solo any basic (and 99% of all) mission in the game. There are a couple Steel Path missions that some frames will have a hard time getting a reliable build for.

I use my Gauss and Wisp more than my Titania and Mesa. That being said Titania and Mesa are going to be easier to get sooner without paying platinum in the Market.

Wisp is my fave out of those.

People seem to like Gauss, but I haven't really figured it out yet

Wisp is amazing. Gives great buffs too

Titania is fun for speed running some missions

Mesa's ult is basically a rapid fire aimbot

In short, they're all good for different reasons and styles

Well depending on your mr and weapon, gauss and wisp is going to be a hard farm. But they are stronger warframe in terms of solo play. Especially wisp.

Titania is the 3rd choice for me, especially in open world she is op. Now as for buffs to allys, the killing monster and getting buff, its titania. Its her skills. But id chose Wisps buffs any day of the week.

Last option for me is mesa. she is easy to get but the judgement point farm and low drop rate can mean u can be very unlucky and spend way to much time behind mesa.

Edit: I think gauss is the hardest to farm due to standing required in 2 fing places. But having 15 plats solves that issue

one thing you really have to consider when you are new is your energy economy. it can be very challenging getting enough energy to use abilities early on. i got mesa very early and then barely used her for ages because i couldnt even keep her 3 up consistently or use her 4 much and at that point she kind of sucks.

on titania with bad duration/efficiency mods and no energize or energy subsumes you are going to be able to stay in razorwing for about 30 seconds at a time which isnt great.

im just going to recommend nezha even though he isnt on your list.

Gauss - He runs fast, can become virtually unkillable with his 2, and his 4 supercharges his weapons to ridiculous levels. Recommended if you prefer to focus on gunplay and moving through the stage blasting everything on sight. Tied with Mesa for hardest one to get form the list, found in reward rotations from Sedna's C Disruption rewards.

I find that his 3 is kinda crummy, and usually replace it with Energized Munitions so I can go full roflolstomp with the Acceltra.

Wisp - Very powerful support frame that can buff her allies with massive health and regerenation buffs, as well as movespeed and attack speed buffs. Her 3 can blind enemies and massive increase the damage they take, and her 2 is very useful in Spy missions, as well as to give yourself a bit of a breathing room in tense situations. Her 4 is not very effective but is fun to play with. Highly recommend to get as she's useful in all levels of play. Second hardest to get, farm Ropalolyst in Jupiter.

Titania - Somewhat gimmicky. Her 1 is decent CC and can grant her status immunity, and her 2 provides some marginally helpful buffs. Her 3 kinda sucks, but her main draw is her 4, which turns her into a tiny Archwing that can rip enemies apart and summons distracting decoys for defense. Not the most efficient frame, but powerful in her own right and a lot of fun to play. Easiest one to get, just complete her quest.

Mesa - Her 1 is fucking useless, subsume it immediately. Her 2 massively buffs her damage, her 3 makes her almost unkillable, and her 4 just aimbots every god damn motherfucking enemy out of this plane of existence, probably one of the most efficient killframes in the game, though I personally don't enjoy playing as her much. Somewhat difficult to get, since you need Mutalist Nav Coords, and those can only be relieably obtained from Invasions.

So I only have Wisp and Titania out of those, and I was sooo excited to get Titania, and I loved her kit when I leveled her up. In fact I used her to farm Wisp from the Ropololyst. And after I finished Wisp I have played Titania for about 30 mins. So I would say Wisp.

Gauss - component drops from disruption on kappa at sedna, one of the last nodes.

Wisp - component and blueprint drops from ropalolyst on jupiter, only unlocks after completing the sacrifice.

Titania - component and blueprint unlocks from silver Grove quest.

Mesa. Goddamn Mesa. Drops from mutilist alad v but to even unlock that node you need coordinates which randomly pop up in invasions.

So from easy to just buy the prime:

Titania > wisp > gauss >>>>>>>> Mesa

about the character with 4 buffs, you could be thinking of Titania, whose second ability extracts a team buff of your choosing by casting a spell on an enemy (usually doesn't kill that enemy though). these buffs aren't the best, but are better than nothing.

• Thorns give you and your team a damage reflection buff, where 50% of damage taken is removed and reflected onto enemies. good for survival, but don't expect it to do meaningful damage.

• Entangle gives you an aura slows nearby enemy movement. i don't think it slows their attacks though, which is mildly annoying because they can still do the same amount of damage per second.

• Dust is an aura that reduces enemy accuracy.

• Full Moon is an aura that buffs your companion's survivability. it also buffs her teammates' companions and Titania's razorflies. probably the least useful out of the 4, but still, better than nothing.

there is also Octavia, who gives 4 buffs to herself and her team if they perform actions to her music's beat as if they were playing a rhythm game. these buffs are a bit more useful to her team imo, but players rarely go out of their way to trigger the buffs, except for one of them.

• Vivace is a speed buff gained by jumping in sync to Octavia's music melody.

• Opera is a multishot buff gained by shooting in sync to Octavia's melody

• Forte is a melee damage buff gained by swinging your melee weapon in sync to Octavia's melody.

• Nocturne, the most important and popular buff, grants invisibility for a while if you crouch in sync to Octavia's melody.

most of the time players just spam one action until they get the buff they want because nobody can be bothered with listening close to Octavia's music. often, Octavia and her allies may accidentally activate the buff without realizing it just by doing what they usually do.

there are also other frames with buffs but these two are the ones off the top of my head that has 4 buffs that it can grant to its allies.

other Warframes that can focus on buffing teammates include, but are not limited to, Wisp (her 3 motes of vitality, haste and shock), Grendel (nourish's 3 buffs: energy, armor and strike), Harrow (covenant's invulnerability and critical buff), Equinox (pacify's damage reduction buff or provoke's ability strength buff, as well as mend's shield repair effect) and Hildryn (haven's strong shield buffs and pillage's status-cleansing power)

Not just those 4, you will get many others, too. You never know which one will grab your interest.
