F/SN Cu is considered the most useful 3* and a secret SSR for a reason. Whilst Proto Cu can perform better as a damage dealer he will fall off as you get better Lancers whereas Cu will never fall as "the dog who refuses to die" and even in the japanese version is still a mainstay in many teams due to his tankiness and survivability, the only servants that beat Cu in surviving are, ironically, Alter Cu and Heracles because they not only survive but can also dish out a load of damage.

In terms of Caster Cu he's a different beast being a Caster. Unless you have a 4* imo He's probably the best 3* Caster; His kit gives him decent stargen and tankiness, his NP is also great at clearing the battlefield and making enemies squishier and when he gets his strengthening quest it's alot easier to generate.

Whilst you have Cu at only NP1 the difference between NP1 and 2 for Gae Bolg isn't big enough to warrent using Proto Cu over Cu.

In closing unless you really, really like Proto Cu I would advise leveling him after Cu and CasterCu because whilst useful especially for early stages and against beasts he is just not good enough to be used over his mature F/SN Counterpart, Though it is really up to you.
