Which Linux Distro Should I Choose for Security and Usability?

There are numerous options, but I'd suggest sticking with Arch if you want flexibility and a chance to learn about setting up a secure environment. You could also consider Fedora, which has great security features and is user-friendly. If you're looking for something different, OpenBSD is another solid choice, though it's not Linux.

For a balance between security and ease of use, I recommend sticking to major distros in the Ubuntu family, like Mint. They offer a solid GNOME experience and a secure environment. If you're willing to experiment a bit, Manjaro gives you that Arch-like freshness without the heavy lifting. Also, you can always test these distros using USBs to see which one you prefer without installation headaches!

You might want to look into Debian 13 with GNOME. It's stable and has a pretty good user experience with GNOME. But honestly, as a GNOME fan, you'll enjoy either Arch or Fedora too.

If you're still open to exploring options, how about trying Linux Mint? It's user-friendly and has a nice GNOME version. Another option could be Manjaro, which is based on Arch but aims for a more user-friendly experience.

I think Fedora Workstation could be a perfect match for you! I've been using Arch + GNOME for a while now and it's been really stable. Just remember to install "gnome-shell" instead of just "gnome" to avoid some outdated apps. Also, check out extensions like PaperWM for a neat workspace!
