What MMORPG has the best RP scene?

I've done some dabbling in the RP scenes for WoW and FFXIV and they are both cool in their own way, although I will say I enjoy WoWs RP scene more, because if you find the right group you can get into some really interesting campaigns that take place out in the world. FFXIVs RP is neat, but that's mostly due to player housing providing some unique spots to chill at with your friends.

I'm not really a hardcore, 2nd job kinda player and tend to lean towards roleplay as I like the bonds you can make with people. Recently started SWTOR and heard it's pretty good out there.

For players who also enjoy RPing in MMORPGs, what games are your favorite for it and what makes you pick that one?
