i got mine when they first released it. almost a year after i almost sold it. if i did, i would have regretted it. the U2 is the best all around use. using rechargeables around the house gives you guilt free lumens. the 1-6 level settings was very useful when i went camping, better then the L2 which only gives you 2 and the highest setting on the L2 can heat up pretty fast and the lowest may not be bright enough. plus the L2 can not take rechargeables. the U2's beam throws a bit further then the L2 due to the larger and deeper reflector but still gives you very good spill/flood cause its a 5w LED. the size of the U2 may not be suitable for everyone to EDC on their belt or pocket because it has a much larger head then the L2, but i dont have to worry about that cause i would carry it in a bag anyway. there are some ppl though that do EDC it on their belt or pocket and love it. the selector ring is pretty handy. sometimes you might need to use 2 hands but at times i find it better that way cause like the HDS, click, double click, triple click, 100 click can get really annoying especially when you miss a click to get the settings to want. there are ppl who had problems with the clickie failing, but surefire will fix it up for you. another option instead of the clickie switch, you can use the same lock out tailcap on the 6P which will be more reliable overtime due to less parts breaking, but you will have to twist for on and off. again, some ppl like it that way.
