Wildcat & M1X seem like different animals. Wildcat has a nice smooth and wide beam sacrificing throw. M1X is definitely built for throw. It's got a magnificent hotspot but less usable light in its wider spread. I personally think the Wildcat would be the more practical and usable light in most situations - it also has high/low but not programmable like M1X. Depends on need though of course. Both are tops.
I would really like to some day see a Wildcat / Legion II beamshot comparison. Those two seem like they have similar large-hotspot beams. I've been itching for both of these lights.
