Depends on how much effort you want to put into learning a class. If not a lot than go with BRD. Safe class to play with only "one real" rotation that you need to be aware of. Monk is quite fun at least to me, because it can keep me occupied by doing position's, so if you like to move around a lot than maybe that class. Ninja is an easier version of both DRG and MNK imo. Only real mechanic with that class is the Mudra's in which if you have bad server lag, it might not be so good for you cause it has a delay in between each mudra. I know some ninjas that only stick behind the rear of the boss because the only positional, iirc that they have is Trick Attack. There is Sneak attack which is a frontal skill but, often in raids you wont be using it that much. If you can micro manage alot of things than go with summoner if you so wish though I've been hearing its not the best class atm for final coil but hey, many has managed o3ob.
