The real answer is that Comanche vs. Hokum has been modded like hell by the sim community

The flight model is about on par with Longbow. It's plenty hard on full realism, esp. when you are fighting and trying to coordinate your wingmen to do pop-up attacks over a treeline. The Apache is esp. great at this, as you might imagine.
They really miss having a AH-6 for recon, but the Comanche itself is faster and has a periscope so it's the star of that role in the game.
