Very nice AH2 video. I liked the visual effects and music.
Yeah, IL2 FB is a very nice single player game. It also probably gives you more immersiveness as far as the graphics and flight/damage models go. However it does have drawbacks. One there is no massive mulitplayer. There are a few servers which host up to 16 players. There are no SEA events. The gunnery in my opinion is weaker than AH2. But it does offer a very nice ingame film recorder which you can go back, look at, and edit into movies or short clips.
You can find some very nice IL2 FB videos here:

I have both IL2 FB and AH2 so I'm happy. I find myself using IL2 FB to mainly shoot down the computer while setting up some quick missions. I also do a little bit of the movie making =)
