Wolverine is a powerhouse and he’s definitely one of the strongest Xmen. When he last fought S’ym, he was humiliated and utterly defeated. If they were to fight when both fighters were at their peak, I’m confident that Phoenix Force Wolverine would take the win. That guy could probably take down planets and not even S’ym could match such a feat. It would be time for him to take a tough loss. Wolverine wins.
