The 220 can't be angled up to bounce off of the ceiling. That's an unacceptable drawback to me.
Taking good flash photos is very hard. You need to do a lot of research and practice if you want to get good at it. The biggest problem with shooting a flash shot of something straight ahead is that the light level falls off exponentially so things close up are brightly lit and things behind them are not.
Another really handy thing to do with a flash is to move it off of the camera. This can be done with a bracket. That helps remove red-eye problems and adds a bit of texture to the photo. Subjects illuminated straight on from the camera look very flat.
