In the vast majority of scenarios Erik wins
Hank is comfortably the best character in the list.
^I doubt that Wanda could realistically take down Phoenix, considering the later is a cosmic force of nature of near infinite power. The most powerful thing that Wanda has done is alter reality, something that a surprising amount of characters can do (eg Franklin Richards) while Phoenix is the process of death and rebirth, and has a constant effect on the entire universe at any given time.
Wanda didn’t create a new reality but altered the already existing one, therefore Phoenix would still be around. Of course i’ve been talking about the force not Jean embodying said force but I believe my point still stands.
Every time that Phoenix has gone Dark it has taken full teams to even contain it. And as the AvX run showed not even pretty much every major hero and team with Wanda was actually able to beat Scott as Phoenix in a straight fight, they even tried using a dragon.
TL;DR Wanda can’t effect the Phoenix force enough to beat it.
