I also switched from Mac back to Windows recently, and am curious what you're missing.
Scrivener is available for Windows (though I use Hemingway.)
OmniFocus has many web-based alternatives...I use Trello, personally. (It's also a Windows app now!)
Coda -- well, there's Sublime Text, VS Code, or JetBrains' universe of IDEs.
This isn't a critique of what you said, by the way. I do think more info about what you're looking for would be great insight for the folks who read Hacker News -- some of whom might be willing to develop paid Windows apps if there's true demand in those areas.
