I very much like wood elves when they're properly separated from their holier-than-thou high elf kin.
... but I think that halflings could branch out to fill the elves' cultural niche more easily than vice versa, so I'm going to have to vote for them.
EDIT: Actually, thinking further about the idea of riverboat-Traveller or tunnel-rat wood elves, I have come to the conclusion that the above paragraph is completely wrong, and am rather glad that the elves are winning by a landslide regardless of my vote.
