Which sever has the biggest population?

I was thinking of rejoining just to check things out, but someone posted in the DT forum that DT is now dead and everyone agreed, that is the server i use to play so i dont want to even waste my money if this game has even less people than last time i joined.
Which server has the most active people throughout the day and aprox how many if you know? Last time anything above 100 was alot!
