generally speaking keep all 1 stars some 2 stars and all 3 stars but if you need the most useful by the lot the one people usually uses and do level are :

1 Stars : Generally everyone. Among them Asterios, Arash and Mozart is the most useful. Some people prefer Sakaki Kojirou for Assassin but Mata Hari are perfectly good unit later.

2 Stars :

Casters : Hans is a must, Shakespeare if you need buster buffer

Assassin : CA Hassan is among the best assassin

Rider : St. George is a must. Edward teach worth keeping

Lancer : Leonidas is a must.

3 stars generally are worth keeping for their NP 5 but among them the cream of the crop is :

Saber : Faber A.K.A Gaius Julius Caesar.

Archer : Everyone,, srsly there's no bad choice in 3 stars Archer, in fact some of them are downright better than 4 and 5 stars on some aspect.

Lancer : Cu, be it proto or the normal one. If you can handle the manbulge then Romulus for AoE, otherwise take Hector. Once you're feeling comfortable do level Diarmuid for he could cut female damage by 50% (and trust me you'll see lot of female enemy in this game)

Rider : Ushiwakamaru for boss killing, and Medusa for AoE. Later Alexander will be useful so don't burn him yet.

Caster : Medea is generally the top, but Caster Cu are also worth leveling if you could NP 5 him, otherwise Paracelsus for AoE.

Assassin : none are particularly good but Jing Ke damage is the highest but you might want to keep Jekyll and Hyde for late game.

Zerker : Darius for the fastest Np gainer among 3 stars assassin.. but he's big burly man.. and most people gonna recommend Lu Bu if you have Kaleido..but he's big burly man.
