From what I see here, most people prefer humans because of munchkin reasons. Figures.

Humans are easy to RP because all of us(with some exceptions) ARE HUMAN. Elves, on the other hand, are not human (obviously) so it takes some effort to correctly RP them.
I am currently playing an elf for the first time, and I wasn't exactly sure how to RP him, so I made him the stong, silent type(much like myself) with a general dislike for non-elves. This actually worked quite well for him, since his home was recently incinerated by an army of humans, mislead dwarves, and dark/demon elves. Now he's seething with hatred and rage, and he rarely speaks at all.
Changing tone, I'd have to say that I DO NOT understand all of those people who go around saying that elves are tree-hugging sissy-panzies from sugar-coated candyland. Where did this idea come from, anyway?
But, I almost always play elves because I love to take my characters a long way in the game world, and the elven lifespan, culture, etc. are quite helpful in that sense, beside the fact that I just like 'em. Not to say that I don't play other races. I love to play unexpected combinations like Dwarven Monks, Halfling Barbarians, and Orcish Sorcerers or Bards.
One time I played a Dwarven Monk, and at one point during the game a tower collapsed and fell on his head. He somehow survived, and when he woke from the coma remembered nothing about being a monk, but immediately after waking he looked around the room and screamed "WHERE'S ME BOOMSTICK!?" He was so messed up from the accident that his memory was altered and he though he was a rifleman, to the point that the DM let me re-write him as a 'Shooter' class which we wrote up. Variety is good...but I still love elves.
