Ubuntu was my entry to linux as well, 19 years ago. But Ubuntu of today is not the Ubuntu of 15-19 years ago, and not in a good way.

When first coming from Windows, starting with Mint is the safest bet for a good transition because things will work pretty much as you expect them to, and there’s a very helpful forum if you have any questions. But I always say to try several distros and Desktop Environments to see how you like them. Everyone is different and it’s all a matter of preference.

I suggest that once you’ve got whatever distro you decided on up and running, install a virtual machine software such as Boxes (very simple) or Virtual Box (a little more complicated but with more options). Then just download various distros and make VMs for them to try them out easily. Have fun!
