So I'm back to WWII flight sims, where do I go from here?

I used to play IL-2 back in the days (some 5-6 years ago) and had great fun playing Co-op and/or versus missions.

I almost never played pure dogfights and had most fun when playing with a group of like minded individuals trying to accomplish a mission.

So I want to get back into it, buying a new computer and all that and this time get myself a Track IR as well. Have seen a few videos of Cliffs of Dover and they look incredibly good. I got hooked again after playing Birds of Steel a little on the Xbox.

But I'm not sure what game I should try to play and in what form.

My options that I know of are:

• IL-2 1946 + Mods
  I've heard good thing s about HSFX and a game mode called SEOW.
• IL-2 CoD
  Looks good and seems to be great on this ATAG server.
• War Thunder
  Don't know, decided to include but I guess it's more arcade and kind of like World of Tanks
• Rise of Flight
  Looks good but I'm more of a WWII kind of guy

So what game am I missing, who has the great kind of online presence I would be looking for?
Should I join some kind of group to fly with an where would I find one?
Are people playing this cool sounding SEOW or is it too tricky?

Thanks in advance.
