A few good options, but who to choose?

So, I've got a few average-good options to rank up as I'm close to forming the necessary resources, but can't decide. (Although I'm starting to lean towards 6* Masacre or 5* Omega Red)

These are my current 5* R5s.

Red mags cheat code for me to cav. Hands down best choice. Him and warlock.

I was leaning towards OR, but I think I'll probably end up taking Red Magneto to R5 and then OR next.

Do u have suicides? If not then Omega Red is bottom of that list.
