I think it really depends on how you like playing. I've played in clans for a long time now but I'm thinking of taking a small break for a while. When you are in a clan you need to stick to the rules of the clan so you may get more RP experiences but you will need to RP in a way that suits the clan. As a civ you can RP anyway you want and change the way you RP. The main thing about a clan though is you meet people in the community. Through clans you are forced to talk to other DayzRP members on a daily basis getting you to know them. What I would say is if you are new to the community its a great help to join a clan, it lets you meet veterans who have been playing for years and you learn a lot of things about the game you may otherwise not know.
