As the title says, I've been using various flavours of Arch basically since I started with Linux. My very first Linux experience was with Ubuntu, but I quickly switched to Manjaro, then Endeavour, then plain Arch. Recently I've done some spring cleaning, reinstalling my OS's. I have a pretty decent laptop that I got for school a couple years ago (Lenovo Ideapad 3/AMD). Since I'm no longer in school, I decided to do something different with it.
So, I spent Thursday evening installing Debian 12 Gnome. I have to say, so far, it has been an absolute treat to use. This is the first time I've given Gnome a real chance, and now I see what all the hype is about. It's absolutely perfect for a laptop. The UI is very pleasing out of the box, the gestures work great on a trackpad, it's just so slick in a way KDE isn't (at least by default). The big thing though, is the peace of mind. Knowing that I'm on a fairly basic, extremely stable distro gives me confidence that I'll never be without my computer due to a botched update if, say, I take it on a trip. I'm fine with running the risks of a rolling distro at home where I can take an afternoon to troubleshoot, but being a laptop I just need it to be bulletproof. I also love the simplicity of apt compared to pacman. Don't get me wrong, pacman is fantastically powerful and slick once you're used to it, but apt is nice just for the fact that everything is in plain English.
I know this is sort of off topic, I just wanted to share a bit of my experience about the switch. I don't do much distro-hopping, so ended up being really pleasantly surprised.
If you're feeling a little bit adventurous give Testing a chance, it works really well for workstation. I've been using it for nearly two decades and rarely have issues. Just about updates for a couple of weeks after the rollover and you're good!
I may look into some of that stuff down the road but tbh I won't be doing anything too intense with it. Web browsing, music, video streaming, word processing and maybe some light C/C++ development. If my needs were more specialized I might consider changing over to testing or unstable.
If you're not looking for the latest and greatest, but just something rock solid with timely security patches, than yeah stable is perfect :)
Sounds like stable should be perfect for you. You can literally keep using stable Debian for decades. It's famous for a reason.
The one trap you have to watch for has to do with adding external apt repositories. If they replace packages from stable you can eventually run into conflicts due to their version and stable's version diverging, which can be very hard to fix and can block all updates going forward.
If at all possible try using Flatpak if you need an app that's not recent enough in Debian.
