My first distrobution was the good old Ubuntu for a laptop that I used for school. I stuck with that for 2-3 years. During that time I really, really wanted to try out new distros, but I didn't want to lose my files and such, so I just stuck with it. During this time I also changed my desktop's os to Ubuntu, but I am not sure when I did it.

After I got a Laptop due to the previous being old and broken, I tried out Arch Linux and grew to love it more than Ubuntu, so I changed out my desktop's os to that as well when I got a new ssd and was migrating to it. I used Arch for another year or two, before my laptop had a disk failure and I had to reinstall. I installed Debian onto it, since I was feeling lazy and didn't want to go through the mess of installing Arch again. And then later I also installed Windows on it with dualboot for games that didn't want to work with Proton.

So basically I now use Arch on the desktop and Debian/Windows on laptop.
