I started using Linux when Ubuntu 6.04 came out. My brother showed me Ubuntu and I loved tinkering with it. Funny thing is back then it was very rare to install Linux and have it work out of the box. Every upgrade was almost guaranteed to break something.

Now-a-days I recommend starting the Pop-OS since Canonical has decided to do a bunch of dumb stuff over the years. Once you get moved advanced you can move to Debian, Arch, NixOS, etc. Cool thing about Linux is there are tons of different setups, you can customize it as little or as much as you want.

My advice to a lot of people trying to learn Linux: Make Linux your primary OS, you will learn it much faster, don't dual-boot and switch back and forth. Having Windows as a fallback will make you learn Linux much slower.
