I just started to make the transfer to Linux from windows. I have limited experience after running Ubuntu on a dual boot laptop back in school a long time ago. It wasnt my daily driver at the time but class required it.
I recently downloaded fedora onto a desktop and it has been a horrid experience. It's sooo slow compared to when windows was on the same hardware. It's so bad the kids won't use the computer unless it's the last one available. I regret the switch, but want the results. I cannot seem figure out what's causing it.
A typical way would be using xfce's "enable display compositing" setting with a graphics driver that doesn't support proper acceleration.
If your hardware is supported (e.g. WiFi chips and GPUs are definitely a valid concern), I know of no post-install config that Debian with Cinnamon needs that you'd not also need to do on Windows, and Microsoft will put ads in your start menu for the trouble of buying their license at that
Reality is most people aren't sensitive to whatever it is these people believe they are perceiving and will get on fine with whatever the defaults are.
