GWEN or Nightfall

Ok, so I feel like dishing out another 35€ for GW, but I don't know on what.

Nightfall with the new campaign, more slots etc
Or GWEN, the newer expansion pack.

The final deision will depend on where I get the most fun i.e. find other basiners to play with easely.

So where are most peole haning out? GWEN PvE or Nightfall PvE? http://www.theamazonbasin.com/gw/forums/index.php?showtopic=9247
