Stay away from Chaos everybody i know who did play them have either started playing space marines, because you can make a better Chaos army with the SM rules but I digress.
I started with tyranids; and that was a lot of fun, but it is a hard race to play against armor heavy lists and it teaches you some bad habits that do not go well to other armies.
