Which mutant to rank 5 first

Ted_n00bgent

I have a mutant 4>5 gem that I want to use. The two that come up most often in the conversation are Archangel(sig 1) and Stryfe. Ideally I would like to r5 them both and collosus as well. I have completed act 6 and have done initial clears of variants 4 thru 7 if that helps for exploration or monthly eq options. I will be trying to work for t5cc next so ideally someone who can help clear the content for it.

Who would you prioritize and why?
