I recently got into a forum conversation on 4seasonsgaming (Australian community site) about what they want for an upcoming tournament. I voted for TDM, or CTF if they played 5v5. I have many great memories from playing in Barrysworld/Savage etc in the 5v5 format. Some people are very divided on which they prefer. I understand USA always did 4v4, and yet EU always did 5v5 (I know this might have something to do with community size) but interestingly Aus went from 5v5 to 4v4 over the years. I'm not sure what the EU uses currently as the main format.

Anyways... what do you prefer? 4v4 or 5v5? What are the main differences between them. What's more fun? What's more professional? Opinions!
