Which server would you pay for (or not) and why?

So in my opinion, I would say there are mainly 4 prominent chess servers that do a decent job in terms of user friendliness. Chess.com, [other chess sites -- VP]. Now you may ask, "why not [other chess site -- VP]"... my issue with that is, for a free site it lacks the quickness of everything else. The reason I added FIDE is because they do offer arena titles. So if you were going to pay for one, which would you choose and why? (I'm not asking for worth it, necessarily, I just want to see why people choose certain things or why they may choose to go with certain places, over others)

EDIT: Reason why [other site -- VP] is there, is because it has been a dominant place for good players (is what I'm told at least) and has a good base because people pay, so there's no reason for people to screw their subscription... As for [other site -- VP], it's free and adless with a lot of variants.

[chess.com doesn't allow comparisons of competing sites in the forums -- VP]

good enough?
