I use and recommend Qwant or DuckDuckGo

Debian Testing (laptop, workstation and RPIs) since it works best for me. Tried Gentoo, Arch, OpenSUSE and several others. Also, I’ve been using FreeBSD for some time.

i3. Superb for keyboard-driven environment. Ultra fast, so responsive and configurable. The best.

Go AMD.

I’ve started several decades ago, with some ancient Slackware (?) version, downloaded using 56k line modem as 1.44 floppy images. Meanwhile I had a period of a difficult relationship with Windows (2000 was the least bad) and a longish affair with MacOS. Now Linux-only everywhere, for the last ~5 years.

I don’t know if it’s the best, but kitty + zsh has been my daily driver for many years.

to $USER/.config/gtk-4.0 and $USER/.config/gtk-3.0 should do the trick.
