"Windows good, you can't change my mind!" doesn't add anything of value to the conversation, especially for people who aren't dead-set either way.
If you swear by windows, you probably have good reasons. People who like windows would love to hear them. Otherwise, why partake in a conversation that frustrates you at all if you don't want to argue in support of your opinion?
+1 for the windows camp: Personally, I haven't found a better alternative for running Adobe programs on good hardware without taking out a loan on my house (mac pros are a no-go). So Windows works best here.
Another +1 for the windows camp: Gaming (but SteamOS is starting to compete here).
Other than that, I have found that some variant of linux or macOS outperforms windows in every way for my needs (insert obligatory, YMMV), and I am happy to list those out if anyone is interested or needs help deciding which OS suits their needs best.
