I put Win 10 on a desktop and hate it. I can't find stuff or do things I've been doing for years on Win 7. I'm in my 60's and haven't found one contemporary who doesn't hate Win 10. I still have 7 on my laptop which I use all the time. I asked about alternative operating systems and Linux was suggested for what I do.
loneryder, like you, I am in my 60's and hate Win 10. I mainly use a desktop with good old Win 7, which I am very comfortable with. I bought a laptop last year with Win 8 to do secure banking and retirement fund management. I really, really, hated Win 8 so was more than happy to do the free Win 10 install when it was available. With Win 10 I was able to change the desktop to "look" like Win 7's desktop, meaning that the big "app" "tiles" of Win 10 all over the screen are eliminated.
Over a year ago I became curious enough with Linux/Ubuntu that I bought a refurbished Dell Latitude D620 with Ubuntu from an Ebay seller/refurbisher. My only previous experience with Ubuntu was with a much older, borrowed, IBM Thinkpad running Ubuntu that died shortly after I got it, so didn't have a lot of time to do much with it. Ubuntu on my current refurbished Dell Latitude took me a few tries to become comfortable. It also had a couple of quirks from time to time, but they weren't terrible. Over the months it began to run slower, which I thought was due to age, but then, a few weeks ago, an Ubuntu update became available, which I put into the machine, and it now runs faster than even when I first got it.
If my Win 10 laptop that I do finances on breaks down, I would seriously consider replacing it with an up to date Ubuntu or other Linux type laptop.
Having no experience with other Linux or versions of it, I can't say anything about them other than BITOG posters seem to like a number of them. Since I do have experience with Ubuntu, I can say that I have been satisfied with it, but only do web browsing, a little word processing (the free Ubuntu version), and email. If other software, or peripheral hardware, is important in your computer work, that may play a part in which operating system you choose.
