I don't know how one can't see the appeal. Once I installed Rectangle on macOS I can quickly put windows side-by-side with a couple of keystrokes, and change which windows I want side-by-side extremely quickly
Fiddling with the mouse to resize windows manually or having windows overlapping and covering up information on each other is not really a great way to interface with them. Maybe it's helpful to locate the windows and bring them into focus, but once they're in focus and in use, I want to be maximizing their screen real estate and making sure they're 100% readable.
And, really, it's something the OS should have had at the very least as an optional feature for over a decade now. Windows introduced this feature in Windows 7. It's been a sore spot of a missing feature and it's especially detracting for the Windows users that Apple wants to have switch over to the Mac platform.
