I have both types of motors and I love outrunners a lot more than my geared motor. I have had a few light crashes with my geared motor and I have ended up bending the prop shaft a few times. I've bent a few back into place but I've also purchased a few new ones. I've also crashed the outrunner but havent had any problems with the prop shaft. The geared motors are louder. I never noticed how loud it was until I started flying my outrunner. It runs so smooth and quiet. I like things simple so I think that geared motors add complexity. You have more parts such as pinions, gears and shafts that break and wear.
