I carry an ARC AAA premium and an Gerber Infinity Task Light.The gerber replaced my CMG infinity that was lost.Pros are common power cells and basicly no moving parts.In this I mean there are no push button or internal switches that can fail.The connection is direct contact on the battery teminals.
The cons are the AA Gerber Infinity is a little thick for pants pocket carry.The other thing is the Gerber turns on by twisting the tail cap instead of the head like the ARC AAA or the CMG.This is just picking nits and I find they are both "Bomb Proof" pieces of gear.....
