I pulled 5 star Diablo

I recently pulled 5 star Diablo from a 5 star nexus and was wondering if he is any good unawakened?

He doesn’t need awakening and only benefits from it if you also run suicides. Congrats, you got a really great champ :]

He’s an excellent champ from the get-go who only gets better once you awaken him, get suicides

Okay I'm going to take him up to r4 right away then.

Also would Guardian be better cause that was the other good option. I also don't have a 5 star tech awakening gem or any tech sig stones.
