I'm using a combo of Linux and Windows 7. Because every Windows since annoys me somehow, be it their obsession with flat UI design, or 'life as a service' or promoting their latest AI experiment.
I really wish Linux didn't double down on the whole flat UI bandwagon. It's getting increasingly harder to find a way to skeuomorph it and have the apps match. Closest is Q4OS but even it has issues with specific sites (requiring me to use Firefox Quantum which I despise as it's uncustomizable, or Chromium which has its own issues)
Windows 7 is unsupported but you can still find modern software that runs on it (MyPal, Panda AV, Pale Moon to name three), but unsupported Linux remains a stuck in time dead animal, with ZERO support once the repos shut down. Sure, I could install Feisty Fawn from 2009, but good luck browsing the web. Same year Windows 7 came out, and I can still use YouTube and modern browsers on it, but nope for Ubuntu Feisty Fawn. It's not alone, Mandriva 2010 equally useless. You'd think the community wouldn't abandon old Linux as easily, given it's FOSS as well as less attacked than an unsupported Windows OS. I expected Linux to be far more future proof than Windows. Boy was I wrong.
