Going by my knowledge of the X-Books, I will say yes. I plan on reading the beginning stuff, but I started with Claremont last story in the 90s and Xavier was decent. It was a vast contrast to watching him be this liar in Bendis story. He was also kind of a douche to Eva when she time travel back to get him to undo that mess was Matthew Malloy. The fact that he waited until he died to reveal that a Omega level mutant would be unleashed now that he wasn't there to keep Malloy in check was so jarring to read. The fact that he left that burden on the X-Men without discussing it with them was even more jarring to read.
