It depends what you want it to do. For basic stuff, linux desktop works fine. If you need specific software i’d look into if it’s doable and how hard it is first.
Linux by default runs fine and without issues, if you pick a distro with stable releases. If you go with something like Arch, you likely will run into issues. If you want to do heavy modifications or run fancy software, you tend to run into issues. Thing about the fancy software is, it tenda to only work properly on linux, hence the issues being linux related.
If you’re a gamer, just don’t. A lot of people here will say you can run almost any game easily, but you usually need to do some fancy commands per specific game to get it to run properly. Which is fine if you just play one game occasionally, but if you hop between games or like buying the latest games, don’t.
If you have a specific preference for desktop environment, make sure it comes with the distro and is well supported by it. You can install whatever you want on any distro, but you have more chance to break shit.
I’d go with Mint or Ubuntu for your first try.
