Familiarity: I've put it through the wringer
I just got my second pair. The loft in the pair I bought in 2009 had compressed and they weren't holding up to the coldest days. Granted, they probably had 40 ski days. My new pair is great in below freezing (-5F) up to 20F. If I'm wearing these on a 30F day, my hands are boiling. I'll switch to my old pair on those days, so this pair will last longer and my hands aren't sweating. I like the free index finger for dexterity and find the glove to be warm enough for almost* everything we experience in Northern UT.
