My longest played character was an Axani...they're Lawful plane-touched, but look human.
My second longest played character was a Gold Dwarf, who was awesome, though people thought his weapon was overcompensating for something.
I think my favorite race to play, though, is human: I fall into the "extra feat" trap almost every time...but, I think I end up playing non-human characters longer, for some reason. I had a changling rogue who was quite fun...a Githzerai monk who was also cool...
I guess I just like races that look more or less human, is all.
