I'd vote but my favorite isn't listed
Granted Scorpious2k's server is just getting started but the GMs are super friendly and helpful too.
(can you tell I'm a GM there?) If you are looking for a server where the MOBS walk around, instead of standing in place like statues (we've almost got the boats working too) come give us a try...if you have any problems, just give a shout and one of us will be happy to lend any assistance that we can.
S2k all the way!
