Favorite is probably Hero. The way the class is designed just looks really cool to me, and their stats are usually very well balanced. Several of my favorite characters fall into that class as well (Ike, Greil, Selena).
Runner up is Wyvern Lord. It has the high defense of armor classes and the mobility of the horse classes. Magic and archers are a pain, though their high mobility makes them versatile enough to never have to deal with them. Depending on the game on how it calculates damage, they might even be able so survive an arrow or two, which is rarely the case with pegasus units.
Least favorite is almost any Laguz class. They look cool, but they were never viable for me in comparison to beorc units in any of my three playthroughs of FE 9/10. The only ones I really got any use out of were the endgame ones...which I groaned about for the same reason I dislike pre-promos.
The herons were good though.
