Ultimate keychain light?

Looking for opinions about the ultimate keychain light. Yes this subject gets talked about frequently...but is there a consensus on the best? The king of keychains if you will?

Which light has the absolute best blend of performance, size/weight, durability, longevity etc. ?

I pocket a quark mini 123, and just bought a T1A Titan to replace it with.

I currently have an eGear pico light on my keychain, and I've also had a Photon II micro previously.

I've been checking out the fenix e01, and the e05. Would these be an upgrade? They look quite a bit larger. Just looking for something for backup only, as I always have a light in my pocket.
