I would have to say Castrum Meridianum. Haven't done Praetorium yet, but Castrum Meridianum is quite fun. Although it's pretty straightforward and not that hard, there are lots of different kinds of events you have to do.
I just played Castrum for the first time last night. We beat it, it had to be done. Now, if you enjoy 8 man heavy straightforward two hour grinds on fairly simple bosses for little reward (no drops and only 100 stones?) then this one is for you. Not to mention you have to be level 50 so it yields no xp. Personally I like the dungeons where the chance of reward are much higher.
I personally like the stone vigil because the dragon at the end drops some insane weaponry. But I am hearing good things about Aurum Vale. Edited, Sep 5th 2013 9:27am by Valkayree Edited, Sep 5th 2013 9:28am by Valkayree
