Also I like using one-handers because I feelt their increased number of attacks per second trumps the increase in raw damage you get with a two hander. Of course I may just think that way because I am using a Monk with Life on Hit on both weapons. Most of the time I'm able to leech more life than the mobs take off (except those stupid never to be sufficiently damned Fast/Molten/Desecrator mobs which regularly hand me my ass).
+ Damage helps like you said and combine that with increased Attack Speed to get some impressive numbers. I've tried to have a decent to huge increase of my main stat on every piece of equipment.
