I personaly think they are quality bits of kit. But they are noisey and do generate complaints at some airfields or private strips.
Might I add (and open myself up to flaming) if you are worried about noise the AC will quiest happily fly on 1 engine. If i fly at unsocialble hours I cut the rear engine for approach (just need to make a go around decision early! and it will go around on 1 if you dont want to climb fast). Although i would not recommend it to anyone. Plus it is good practice for when you really loose an engine.
You dont have to worry about asysmetric (or however it is spelt) thrust. It has fairly good STOL abilities and it can lift a fair bit of weight. Unless you get a belly container thingmjig there is not much storage inside if you have a full load of pax.
There is plenty of room upfront, th epanel is quiet large so if you are short you might want a cushion to sit on.
