Everything you're describing in this reply just exhausts the hell out of my brain. You're describing an incredibly large amount of cognitive load you hold in your head all the time about where things are and what they mean and how much of them are visible.
Tiling WM are largely about just not thinking that much about windows at all. They're visible or they're not, they occupy precise areas on your screen, and moving them around is easy and simple and they don't scatter to the 4 winds when you plug your laptop into an external monitor and then unplug it again.
Every time I have to go use a computer with overlapping windows I suddenly find myself thinking about where things are about 10 times as much and it's frustrating and tiring.
