Couldn't find a post that specifically addressed this question.

If I buy the Lord of Ogham or King of the Faridun Supporter Pack, is that going to give me better value than if I simply added the dollarydoo's to my account later.

Basically is:
The King of the Faridun Supporter Pack contains Early Access to Path of Exile 2, two Armour Sets, two Back Attachments, a Level-up Effect, a Hideout, three Weapon Skins, three Pets, two Hideout Decorations, a Portal Effect, two Portrait Frames, two Forum Titles, two Badges, and 1000 Points.

Worth more than the $100 difference from the base EA access?

ALSO: Do I get to pick the pet, portal, skins etc?

ALSO ALSO:

If I have already bought the base EA, can I just pay the extra? Steam seems to want me to but a second EA key.

Note, I might be really nice and donate the extra key to a helpful Exiler (or whatever you call yourselves!)
