I've never dragged a window between screens on Windows because that's not something you do on Windows. You use win+direction. Something sorely missing from osx and third party software is nowhere near as good as the native Windows solution. I use both OSs almost everyday. Mac for work, and win for home. The fact that you mention dragging windows (a necessity on mac) in Windows shows that you probably don't use it very much or don't know how to use it conveniently.
I enjoy both OSs (the UX is basically 90% the same btw), they're fine. And there are areas where one works better than the other. By focusing on the issues with one of them without realizing the issues of the other just shows that you're probably not familiar with the other.
I'm not disputing your point, just showing your partiality. I've literally not had to "manually" resize or drag a window in Windows since Win7, but I do it everyday on mac. The Windows model for window management is just better, but you'd never hear it in these comments.
