I still have one from ~10yrs ago and it still works! Its been through the wars, upgraded RAM and SSD, but it dual boots windows 7 (no judge plz) and ubuntu (i said no judge!).
I use it mostly to watch youtube video guides in the workshop when Im working on stuff and dont want dust and sparks inside my regular laptop.
"Best" is very subjective, particularly about Linux.
Are you just wanting to experiment with Linux, and don't have much in the way of a "tech" background? Do you want a distro that more or less works right away after installation? Then Ubuntu (or one of its many derivatives) is probably the better choice for you. (I personally like Mint).
Are you a power user who compiles drivers for fun? Do you think that starting your PC after uninstalling your bootloader sounds like a cool puzzle to solve? Then you'll probably find Ubuntu too restrictive.
It's a very popular and user friendly distro, often recommended for beginners.
But it's not just a beginner distro, it is also very versatile/powerful and well supported. So it can be used just as well by experienced power users.
The reasons to use other distros is not so much about what you can do, but more about how it is done.
