I had issues with drivers, like I would have to find them somewhere on the internet, trust a random stranger to download and install them. And even then some things required me to launch drivers manually every single time I wanted to use my hardware.

I had issues with games, constant crashes or some games flat out not working. Some even crashing the entire system occationally.

I had issues where my pc would randomly turn on. Going to sleep was funky and would break the system requiring restart. I had to find drivers for my audio systems to get them running.

I had to run around confusing settings and tweak them through different control panels made by random people that largely overlapped to fix basic issues.

Thankfully those issues were solved the moment I installed linux.
