My first radio was a single stick. Rudder & elevator and you put in enough glow fuel for three minutes. Every landing was dead-stick, but we all started out with powered gliders so it was all part of the experience. Ah, the simpler times.

But I've never lost an airplane (knock wood) to a dead-stick.

I wouldn't go back to single stick now. Just too used to double. I don't think I could coordinate a turn. As mentioned, it's all what you're used to. It should also be observed that the beautiful Kraft single sticks were wonderful transmitters . . . but did not survive into the 21st century. If single stick was inherently better we'd be wondering why double sticks were no longer made.

Then there's Mode 1 vs. Mode 2; but that's another topic.
