GMT Time zone (Server Transfer)

So I'm currently on Adamantoise due to me coming to FFXIV with a guild from another game unfortunately most of that guild has either quit, rarely plays or comes online at times that are inaccessible for myself.

So the aim of this thread is to find out which server has a large GMT player base so I can come over and hopefully join a FC within a time zone that has more to offer me. I'm at the end-game so i'm looking for a server with a few FC's that are both English speaking and doing alot of the end game stuff.

Thanks for reading.

Behemoth, Tiamat and Tonberry.

Behemoth and Tonberry are blocked though.

The ones I've seen and been told to join are either moogle or odin, however I'm unsure which one I should join, and which has FC's that are willing to welcome me with open arms haha.
