In a serious Head-to-Head battle who would win, the Avengers Or the X-Men. This is a very hard decision, which i need other people to help me decide.
It depends. Which team is Wolverine fighting on?
All vs. all in best level would come to:
HOM Wanda + Shuma Gorath Stephen Strange vs. Legion + White Phoenix of the Crown
Currently - Phoenixes stomp. And Rachel attacks Wanda on Astral Plane.
Jeffers + Danger > Iron Man in technopaty, so Emma will be able to take out most of Avengers by TP.
Controlled Avengers fights with Rulk and Juggy with Thor. Magik and Cuckoos takes out Strange and then helps other X-Men (including Magneto and Namor) with Thor. So many different attacks on the same time (a specially Magic's soulsword), should be a problem for Thor.
