I feel I can offer a nice perspective on all this as I'm basically what Sephiroth is accusing everyone in here with a different opinion than his of being. See, I once gladly ignored the Compilation and thought my ideas were right.

I did this out of love for my first ever Final Fantasy. I wanted FFVII to remain as it was - perfect.

But alas, we must all grow up and realize this world we live in sucks.

So the Ultimania does exist. Advent Children does exist. Crisis Core does exist.
I think everyone in this thread acknowledges their existence and validity.

But then again, we also know of the Prequel Trilogy. Star Wars fans have to accept midichlorians exist too.

It has nothing to do with thinking your opinion is more correct than the "canon' one. It has to do with wishing to preserve, if only in a pretend fantasy world, something of beauty.
Fantasy is always preferable to reality and the fantasy that Crisis Core doesn't exist is one that I love.

The only good thing to come out of the Compilation was Cloud's outfit in AC. Pretty sexy. Not a huge fan of the shades but they were okay.

In the end, let everyone think what they want to think. Enjoy what they want to enjoy.

Also, champagne supernova, you the one from Naruto Forums?
