I fly both for sport and pattern. This 2 stroke is better thing makes absolutely no sense. I know that if I want smooth power to pull a vertical the 4 stroke delivers without waiting like a 2 stroke to reach speeds and the power band. Also, a lot of things are better if you have torque available immediately and without the high RPMs all the time. You can fly smoother with a 4 stroke unless you have a really overpowered engine that will pull a plane around *smoothly* at 7000-8000 RPM.

One thing nobody has mentioned is that you can have a lighter plane if you have a 4 stroke since you don't need to carry around a lot of fuel. How many 2 stroke planes can fly around for 12 minutes on a 5 oz tank? Not many.

If you are hyped up about wiping a plane down at the end of a day, 2 and 4 strokes alike, just use some polymer based wax on the covering and it comes off in one swipe. And, the plane looks better too.

Who cares about noise? I like loud planes! Too many people whine about noise.
