Hey all i just have a simple question

I know there a two role-playing realms (english ones) in lotro and i wonder in which one of them (laurelin and landroval) people role-play the most?
My point is one of them is a realm where some specific events take place and the other (atleast i hope so) is the one where everybody is always in-character and this is the one im looking for,so i mean where are the most roles played on?

P.S if you played WoW i mean im looking for one that looks like Argent Dawn EU

Thanks in advance..if you help me i mean
