The 21st century series was very biased against the X-Men. The original X-Men vs Avengers series from the '80s was a bit biased against the X-Men too, because it was written by the regular Avengers writer. But it wasn't anything like this thing. The recent series sets out from the beginning to vilify Cyclops. And it's incredibly stupid how the Marvel universe managed to find itself in a position that resulted in Wolverine being on the Avengers side, rather than the X-Men's. The whole nonsense about Wolverine and Spider Man being Avengers this century is a load of bull. I think even Doctor Strange has been an Avenger at some point this century. I mean I wouldn't be surprised by now if they made Galactus or the Juggernaut into bloody Avengers.
All of the above is a classic example of how Marvel comics have gone crazy in the 21st century.
