You're not alone. I made the switch this year. Primarily for working on an iOS project. There are days I miss Windows quite a bit. For most things, animations are minimal. Things just pop up, switch gears, and do what you want almost instantly. Explorer is far better than Finder for most things, even if it's also substantially uglier.

Just for a simple example: I change to arbitrary folders frequently. Control-L in Explorer, type the path, and I'm there the second I hit return. Done. Finder has a similar method using Command-Shift-G. But not only is the shortcut more awkward but going to the path has a delay. Not a long one. But it's noticeable and annoying.

Oh well. Spotlight does seem to work better than 10/11's built-in search. So maybe it's a wash. Still miss Windows sometimes.

At any rate, I did make one change in MacOS which long term Mac users might find heretical. When using my external mechanical keyboard, I have Command mapped to the Control key. Control (which doesn't get used often) mapped to the Windows / Super key. Alt / Option is unchanged.

It's a bit amazing how much easier this made everything. Most of the usual keyboard shortcuts I had in Windows now map 1:1 on my Mac. Which is great for the muscle memory.
