I hate maximized windows. I like it when my windows are not maximized but I usually do have significant overlap between windows. Then I switch between windows based on the sliver of window that’s visible even when other windows are in focus. It’s the spatial way of thinking; just like how Finder purists think each folder on your disk should remember its own window size and location so you use your spatial memory to locate Finder windows. I find that this is significantly faster for my brain to process compared to the Windows style where almost all windows are maximized and people use Alt-Tab to switch between windows.

I would in fact say that the culture of not maximizing windows was a small reason why I switched to Mac OS X in the early 2000s.
