I've used Linux on my PC and laptop for the past, I think 5 years now? I think I started in Year 7 or 8. Damn that's a long time ago...
Before then I used Windows and hated it, but I've been mostly happy with Linux so far. It requires very little configuration, but if you choose to do so you can customise the entire OS, from the user interface to the core utilities.
I'd recommend Linux Mint or Fedora Workstation for anyone new to Linux, but I personally use GNU Guix System and Alpine Linux for various reasons. ElementaryOS I have heard is quite intuitive to use for MacOS users, so that might be a good choice.
But whatever you do, don't use Windows. My God, using Windows is like dealing with a rabid ape on caffeine - adverts on the home screen, a million security vulnerabilities every month, more viruses than a Chinese biolab, sells your personal data to anyone with the money to buy it, slow as a one-footed octopus with dementia, will "remind" you to try their Microsoftware (which will probably also be complete trash), forces an update on you every other week, list goes on and on...
On the other hand, Linux has only ever been good to me; installing is a 15 minute job, the OS is fast and free of bloatware, it's way more secure than Windows, and definitely more private. You can make it look however you want it to, never need to touch the command-line if you're uncomfortable with it for some reason, and in the very unlikely scenario that something does break, people tend to be helpful and supportive to help you fix things, although I've never actually asked anyone for help I don't think - most things you can just look up online thankfully
So yeah TLDR Linux the best, MacOS not the best, Windows trash
