Believe it or not, I've not had any experience with CTF as I'm fairly new to online gaming. I'm having a hard time with it but part of that is that I'm in rooms with people not communicating or coordinating the efforts. Might enjoy it more with the AVS clan once things are more organized and running smoothly.
With that said, I do like the Zone option. It's a good alternative to Team Deathmatch as you don't have to be as coordinated as CTF but it gives a sense of team accomplishment.
