I have 160 hours in payday2, although I'll admit I last played it 6 years ago, so things might have changed. But it's a pretty good game. In fact, it's actually 2 different pretty good games. It's both a horde based shooter and a stealth heist game, although I think arguably a lot of the meat of it is in the horde based shooter mode. Some levels are strictly one or the other, but some levels are both, but at least at the higher difficulty levels not at the same time.
At lower difficulty levels when you first start out you can in theory start doing a mission in stealth, and then when you flub the stealth you shoot your way out, and it sorta feels like that's the "thematic" way for missions to go. But realistically on higher difficulty you can't really make that switch, you need to build your build so specifically to either stealth or combat that there's no switching mid mission you either start shooting from the start or have to perfectly stealth your whole way though. (Some exception for the dodge build, which can at least try to both stealth and fight, but it's pretty much a bad at both situation).
That said that's not really a bad thing, just a bit of a... not quite thematic thing I found. Both modes I found are quite fun though. Although as I mentioned the actual combat is a bit more in depth with builds and such, whereas stealth is a bit more of simpler side game and to a certain extent is about exploring and memorizing level lay outs, and thus has a bit less replayability compared to the horde shooter mode. I would say if you're at all interested, try both, you might like both modes or might only like one mode, and that's okay.
Edit: If I recall it's a pretty team based game though and probably best with a nice friend group to play it with. So, I guess also keep that in mind and hopefully bring some friends along with you to try it out.
