IEN is offering free online play of WB, WB3, and DOA from the 6th through the 9th of July.
I got the downloads and have only flown them offline for now.
My take: The terrains are not as nice as AH. AH terrains have a more realistic appearance. About the only area enviroment wise in which WB3 has an edge on AH is the water. It's alive and undulating. However their shorelines are not as well done as AH.
The planes in WB3 are nicely rendered, but the cockpits seem dead and lifeless. Cockpit art is nice, but your head seems frozen in space. Some folks complain of the undue head movement in AH when manouvering the plane, but I think it adds life to the cockpit.
One thing I did really like, and would like to see in AH. When you put the plane into a dive, the engine rpm sound would wind up, and in a climb, would slow down as the prop was loaded. This gives you a pretty good seat of the pants feel on your energy state without having to look at your guages. A nice feature that I hope gets incorperated into AH.
I won't go into great depth on the flight model cause it's been beated to death here already, but to me it seems overly mushy, and unresponsive. I don't get the feeling of flight as in AH.
The stall horn is about as annoying a sound as could be found. And does it really have to go off on the take off roll?
Haven't had the chance to try the gunnery yet, or witness the damage graphics from gun strikes, but the tracer effects are weak as compared to AH.
In conclusion, for my money AH is still the best value out there for a good WW2 combat flight sim. I'll be here a while yet.

It's just my opinion, I could be wrong.
