I tried CFX first, but found it to be a pretty crappy, albeit an extremely userfriendly, program.
The problem was untegration with products other than ansy's own.
I just couldn't be bothered to try and learn to use it properly, so I went for Gambit and Fluent instead. Or at least I'm trying to learn to use fluent, but using it requires a little more than just the few clicks of the mouse cfx does, so it could be said I'm still trying to learn.
