New keychain light.Preon Revo or Peak Eiger?

[R.H.Clark]

I've been doing research on both these lights.I am leaning toward the Preon Revo unless someone can convince me that the Peak Eiger is more durable.

What I want is something very close to size and run time but brighter than my ARC for a second set of keys.I would love to see any size comparison pictures of the Revo and Eiger side by side with an ARC.
