Toxe I made the switch to linux (arch btw) and its been painless for the most part.. sure you get to learn workarounds but on windows you do the same with debloating and patching registry to not update automatically or ask for password changes when you dont want to change it etc etc.. I just dont want windows to send and do heartbeats to shady services that i dont know about unless i use a pihole type service where i can monitor whats going on on my local network. Also now the AI screenshotting thing - that was the last straw for me to make the switch.. Can you really trust that you have disabled it?
As for server related, been running my server on proxmox for 2 years, stable as a goat.
As a work pc, loonix is very sufficient if you dont need to use propreitary apps like adobe, autodesk, etc etc.. For gaming, well for my light gaming its been very good, only one game i wanted to enjoy i cant - factorio where i get kernel panicks and my screen freezes up and locks up because of DRM bug thats been there for years and nobody on the FOSS is bothered to fix.. MAybe if i was on nvidia card i wouldnt have to deal with this garbage + the lack of hdmi 2.1 support on amd cards - cant use your OLED TV 4k 120hz on full RGB color space, limited to YCBCR garbage.
