Oh, that's hardly true. The planes with no control surfaces (where they steer by adjusting the power to each of their two motors) fly much worse than the planes with real control surfaces.
`Differential thrust control' sucks. I imagine it could be made to work somewhat acceptably if more care was put into the plane's design and trimming, but none of these cheap models really does this.
Ultimately, you want a plane with at least three channels -- throttle, turning (either rudder or ailerons) and elevator. A V-tail or elevons instead of a rudder and elevator is OK too, but anything that only has two channels (as in throttle and rudder) just isn't going to fly very well if one of those channels is throttle and the other is turning.

Most of these planes do handle crashes pretty well. As you said, having the motor and prop in the back helps a lot in this regard.
