Helicopter flying in FSX?

Many screenshots that are requested by forum members in the screenshot forum end up with a Bell Helicopter over the requested airport. It seems the Beta Testers fly the chopper more than anything else. Tell me, how different is the overall flight experience with flying helicopters in FSX as it compares or contrasts to flying them in FS9?Do you set the realism settings below the "full realism" setting? How difficult are they to fly, hover, and land? I'm not opposed to having to learn to fly a challenging model, but I just want to know how it compares, dynamically, from the current version of FS.
