I switched around 2 years ago after using different distros on and off for a few years on an old laptop, and I've never been happier with my computing experience.
One thing I will say is you will have to find replacements for some of your favourite applications, but I've found that pretty much every alternative has been better. And if you need suggestions just ask the community or you can DM me.
Also just pick Mint or if you really have to Ubuntu(though I would definitely pick mint) as a first distro as that will give you the best out of the box experience and a beginner friendly community( unlike Arch's which I daily drive).
Then switch if you want a different distro( and I would suggest trying it out in a VM), just don't get a distro hopping addiction😆.
As I Linux user I can't wait for the flood of cheap perfectly good hardware from these idiots
