My answer isn’t unique, but Arch linux is just my favorite to use. I just really love the ability to assemble things exactly the way I like them during the installation process.
I also really like the idea of a rolling release distro, meaning no major upgrades. I just run pacman -Syu once a day and things have been great.
Lastly, almost any piece of software I could want is available in the official repositories or the AUR, and it’s super convenient to be able to install things right away from the command line.
Editing to add: My work laptop is a MacBook Pro and I love it. macOS is really pleasant to use and anyone who says it’s not is a liar. Apple’s user experience game is on point
