Base on the movie alone....To be fair and square I would side with Erik.....if I were a mutant.
Professor X high and mighty road is not fit for this age.
meh.. its hard to say, they both have good parts too them. if i HAD to pick it would be professor X because all the mutants on his side are badd a**
like if you watched Xmen 3 all the mutants magneto had just suckedd!! well besides juggernogg (spelling)
