Depends on what you’re doing at University. I was using Arch but an update caused CUDA to stop working so I couldn’t work on an assignment. Why did it stop working? They updated CUDA to 12.3 days before updating the NVIDIA driver to a version which supported CUDA. The maintainers are mostly negligent and the community is rather toxic so I’d avoid Arch for that kind of thing. NixOS looks interesting and has lots of benefits however, for a dedicated University computer I would recommend using the most boring Linux distro available like Fedora or Ubuntu.
