I’ve been using Linux for more than 20+

First distro: Slackware, then Debian for many years, finally Fedora, since 2014, very happy user.

What I like in Fedora: the 6 months release provides bleeding edge experience without compromising stability.

Slackware, in the 90s, installed from floppy disks. I also used SuSE, Debian and now stick with Fedora.

Still using Firefox but looking to move to LibreWolf

If you have budget, Thinkpads can’t go wrong. You can also find refurbished.

Tuxedo and Framework are also excellent choices.
