I like to stick to Elven Telepathy as much as I can
But leaving personal tastes aside, I'd say tier 1 fellowships would be Dwarves, Hobbits (with or without Gandalf) and Ents.
Dwarves can fight, wipe the table consistently with damage bonuses and
Blood Runs Chill and draw cards like crazy. Hobbits can choke, or just be tough, have super vitality and just can't be corrupted plus they have two ring-bearers. Ents just smash everything in their way
Even a c/u ent deck can stand a good fight.
