Honestly, I really don't mind Windows lately. It's a very clean UI and is fairly snappy (Windows 10/11 still aren't as Snappy and lightweight as Windows 7, but for a modern OS, they really don't feel slow). My main gripe about Windows (and pretty much THE primary reason I'm so plugged into the Apple ecosystem) is that I am very worried about the sheer amount of telemetry in Windows. The control panel settings for it are very convoluted and confusing, so I don't necessarily trust that they've exposed all of it to the user. They frequently overwrite settings on updates and there have even been reports of keyloggers in the OS before (not sure if these still exist, there is no setting in Windows 11 for it).
That is just very worrying to me, and is part of why I don't use Android for my phones either. I don't really care too much about first-party tracking (most of that genuinely is just to help the developer), but third party tracking is an entirely different story because you really have no idea where the data is going or what it's being used for. Even if it's just being used to tailor advertisements, how do I know that sensitive data won't be spilled about me if the data collection company gets hacked?
Windows is a nice OS these days, but I just don't think I can quite feel comfortable using it for those reasons. Maybe that's just me (or maybe I'm just worried a bit too much to an irrational degree), but the idea of that much telemetry being on my OS just feels uncomfortable to me.
