Lalafells definitely have the best emotes.
(They're also cute, though that part is somewhat countered by the fact they don't show off cool-looking gear as clearly as the other races.)

That said, I never much liked the lower camera angle, and leveling my lala's archer class is annoying. (She squeals with every shot fired. My Miqo'te and Hyur don't do that. I haven't actually worked on archer with my Elezen or Roes, but somehow I rather doubt they'd squeal like that.)
