Heracles=Strongest berserker in the game. Lancelot (Saber) = OP... He's an SSR that pretends he's  an SR. Artoria Pendragon (Lancer Alter) = Generally strong, not OP but very rare and is Artoria.

I would suggest as #1 or #2 Nitocris but you won't be able to lvl her up till you finish Camelot( Main story Chapter 7)

The ones mentioned first can be usable immediately.
