By software you only mean window management and switching really, then. When you witness a lot less of app crashes on macOS you will appreciate the software better.

Window management used to be a pain for me too on a mac until I found Spectacle. With a few keyboard shortcuts that you set yourself, you won't miss snapping windows by mouse drags. Everything happens with your fingers on the keyboard.

Alt+Tab with multi-window apps is still a pain for me I admit. So I'm with you there.

Overall the stability of a mac (both software and hardware), usability and the productivity you get with the trackpad gestures will make you not want to go back to anything after you've used them for a few weeks.
