I'm assuming you mean "Can't say"?
If so, right. It is a subjective thing. Wanam is better for me. I found Omega bloated and full of things wanam created anyway, so I just thought "Why not go to the source?"
I also thought Omega updated to every new base when it wasn't needed. Even if there was no changes. That's kind of irrelevant now because every new base seems to have something new in it now.
I also didn't like how the Omega developer ignored my posts in his thread with a request. These were all reasons why I left and to be honest, I never looked back.
That said, it really is subjective. One man's trash is another man's treasure.
