Who to rank 4? Onslaught or Mister Sinister?

I have been sitting on a mutant rank 4 gem for a while now because I cannot decide between Onslaught and Mister Sinister. Neither of them is awaken, but I can awake and put signature stones. So, the awaken status does not really matter. I know I cannot go wrong with either of them, and I think I will be happy with whichever I choose. But I am wondering who has more utility and helps me more in hard contents (like saving revives and potions).

Recoil friendly to boot.
Ko’s everything except robots…
Rank him up and enjoy the 50k degen ticks until the bug is fixed....
If you don't have the Apoc prefight, I still do the same thing, but only after my relic is fully charged. That way you can relic intercept (which I personally find much easier than a heavy intercept).
You can also just play around with throwing sp1 as you'll just keep healing from his bleeds. It just takes longer, but you don't have to work about chip damage.
Clouddey_bro said it best above if your goal is saving potions.
