Legion vs Phoenix (Janssen)

Who wins?

For now I'd say Pheonix without a doubt, David is Far too unstable and doesn't know how to use his abilities nor what they are.

However my opinion may change if David is actually a reality warper like the show may be hinting but I could be wrong

The last episodes I watched was him saving his sister and he look very powerful in that episode.

This Phoenix can't tap into the astral plane like her younger version, I guess it depends on who strikes first. But not seeing what's stoping Farouk from trapping her in her own mind like he did to David

If it's normal David then Jean should win
