Whenever I see tools like this for Mac I can't help but wonder if I am seriously missing something.

Unlike when I use Windows, I just don't use command (alt) tab on Mac. I rely almost entirely on gestures on my trackpad (three fingers swipe up to see all my windows that are not minimized).

With the added benefit of that allowing me to drag those windows to other screens/desktops right from that UI.

Is there some power user advantage I am missing out on here or is this sort of making Mac work more like Windows? On Windows I use alt tab all the time just because... I find its windows management sucks compared to Mac.

No, the joke is on us MacOS users who insist on its terrible Alt-Tab behavior instead of leaning into the gesture support.

But I do believe the gesture support has fundamental limitations:

1) you have to take your keys off the home row to render gestures. Not good!

2) gesture window switching / Exposé breaks down when you have too many windows open: the thumbnails become unrecognizably small.

3) to solve the above problem, perhaps you suggest using spaces. Well, MacOS's spaces support is also frustrating. It's impossible to turn off the animation and time lag switching between spaces! Sure, it's only a half-second, but a half-second repeated hundreds of times adds up. And spaces's interaction with alt-tab is totally broken: if you're using a given app (say Chrome), switch to another space where Chrome is also open, and then try to alt-tab back, it doesn't take you back to the last window you had open. Sad!

The space animation lag is mind boggling. Not only is it a half second, but it locks keypress until finished.

Any Apple devs (or anyone) here who can comment about why they removed the expose-animation-duration option?

If you install yabai (https://github.com/koekeishiya/yabai) it has a feature that can completely disable spaces switching animations - but it does require partially disabling SIP (worth it for yabai, IMO).
