General thread to compare n contrast the 2 Big X-men Villains

Each has affected the X-men in various ways. Mag was there from the start so he has had a much bigger impact overall. Apocalypse has affected a lot of characters like Cable, Angel and some others. Not as much as Mags tho.

Who is your favorite and why? If you hate both of them which Villain would you like to see elevated to the same level as them.
