No one from FE1-6 really. Altho Doga and Bors aren't terrible.
Oswin is incredible and Wallace wasn't terrible. Maps were mostly small in FE7 which helped that class.
FE8's Gilliam was pretty solid.
Gatrie from FE9 can be decent-ish...
FE10 Taureneo (sp?) was likely the best from 10. Him or Gatrie. Meg had kinda bizarre stats and wasn't likely to get trained.
Basically.
It's Oswin. Dude is the best of his class by a great deal. FE11 had some wacky stuff with Wolf and Sedgar as Generals but they aren't really generals.
