Zerkers are good candidates for this because of their versatility.

Nevertheless, I opted to max out Tamamo-lancer first and I have no regrets. When I was done with her, I started giving 4* Fou to zerker Vlad. Just as Taufu Boss said, go with the servant you like. The bonus is rather marginal anyway, and is nowhere close to being required by a particular servant at any point in the game.
