Ive had both the jumped crimp issue and the ejector rod issue. Both things I try my best to address, among a few others. All new (to me) revolvers get Loctite on the ejector rod, so that's generally not an issue going forward because of it, and ammo is watched as closely as possible. Once addressed, they usually arent an issue, but ammo always will be something you need to watch with whatever you choose.
Ive had more chances at doing a TRB than revolver issues, but in both cases, I shoot my reloads in practice almost exclusively, and I shoot the brass to failure, so I get to see all sorts of failures, stoppages, etc, and get to randomly deal with them. And since I shoot the autos a lot more, I see more issues there, random as they are. Even then, in the scheme of things, its not something that happens all that often, especially with guns that are known for reliability.
But, that's why we work on things in practice too, and Ive come to find, that worn out brass is a great aid in doing just that. No need to set things up and you never know when something is going to pop up.
I think the point that's being missed here too is, that everything can fail, and the more you're familiar with things that are fairly well known, and even somewhat common, common enough that you know to address things that need addressed, and deal with things you might run into, the less trouble you're likely to have, and if you do, you know what to do to deal with them when they do.
As Ive said before, revolvers are not immune to problems occurring and when they do, they are more likely to be shut down when they do. You don't want a problem with either of them, but if I had to have a problem with either, Ill take the auto every time.
