Android has a far better OTA update system than iOS. The notification system is much better and the default keyboard is better too. It supports multiple user profiles that you can switch between instantly, with their own separate apps and settings and home screens, a long requested feature for iPads that is inexplicably still absent on iOS.

Windows has a better desktop compositor and window manager than macOS. It supports Nvidia GPUs with CUDA. It also has WSL so you can use real package managers instead of homebrew.

"winget configure" is pretty great in Windows - you can store your personal .config file on GitHub and use it whenever you set up a new PC to install everything you want, uninstall all the cruft you don't want, and set all the Windows config you want via registry keys.
