PRS trems are very stable, but no trem is as stable as a stop bar, so it’s hard to compare that aspect... also, stop bars are very hard to divebomb with.
As Steve noted, Gibson has improved in recent years. And even prior, it’s not like there weren’t good, or even great, Gibson guitars. It was the roll-of-the-dice nature of what you might get with their normal line instruments that frustrated players and pushed them to look elsewhere. Thus, it was that “always plays like you expect with a PRS” experience that took me from being a Gibson guy to being a PRS guy.
I know it matters to many folks, but resale value doesn’t matter to me. The “market” value has nothing to do with how an individual guitar feels or sounds. I just make sure I don’t overpay to start with, work on getting a good deal up front which provides value while you own the guitar and a better margin if you decide to sell. I’ve often bought pristine “used” instruments, gigged them for years while maintaining them well, and actually made a profit when I sold them. Made money with them, then made money selling them. That’s value! Pretty easy to do with PRS instruments, and they’re great the whole time you own them, so resale isn’t a constant thought. But I do understand the consideration. I’m just recommending you don’t let it play a major role. It’s like choosing a wife based on how she’d be in divorce court.
I wouldn’t hesitate to own a CS Gibson if I wanted a particular one. It’s just that once I came to PRS as my main instruments, they’ve given me no reason to look back. I’d recommend that experience to anyone.
DGT, or if you’re really looking for a 58/59 LP feel, a Single Cut 594.
