As was mentioned already, it depends on what do you want to be secure from... Squire has some beefy padlocks, that should be very secure against a brute force... EVVA MCS is quite secure against picking... Kromer Protector is considered "unpickable"... As for anti-drill, my bet would be FAB1000 - I haven't seen another cylinder with that much steel in it yet... The reverse sidebar Yuema is considered unpickable too, yet it can be impressioned... Unfortunately there is no easy answer to that question, otherwise there wouldn't be that many locks around. Plus there is the problem of lock not being the weakest link...
Just my guess but a protec2 probably is up there
Secure for what?
The lock is usually not the weak point in access.
Hardest to non destructively bypass?
My bike and my motorbike are secured with Abus top of the line products. Not the hardest products to pick but hard enough that anyone would prefer to go for brute force attack instead. With 2-3 of them I believe I can’t secure them much more.
