Overall, I've had more "issues" with a limited number of semi-autos than I have with revolvers. I've shot far more revolvers than semi-autos.
That said, I have semi-autos that have never failed in any way, and I've had revolvers that disappointed me in their performance.
In the end, it's a matte of finding what works for you, proving it's reliability, and learning to shoot it well.
All else is irrelevant.
