Not the person you asked, but I'm in the same boat. I prefer Linux, but tolerate Windows because I'm a gamer, and I can't fucking stand MacOS. I'll give you my reasons.
- Can't disable mouse acceleration via the UI. You have to use the terminal to enter a command to change a setting that sometimes gets overwritten on a system update. You can't disable scroll wheel acceleration at all without using 3rd party software.
- I hate the dock bar. I want each window of an app to be its own entry on the bar so I can easily switch from one window to a specific window with a single click. In MacOS, starting a second instance of an application that doesn't have a native method to do so is a total pain in the ass. Going to the Launcher to start the program just shows the existing instance of the application.
- Shitty defaults in general. Scroll wheel direction is backwards. Scrollbars auto-hide. The screen color shifts throughout the day.
- MacOS is based on UNIX but always feels like it's trying to hide that from you. The "root" user isn't capable of everything. There are directories in your home directory that even root can't access.
- Home/End keys move the cursor to the beginning/end of the document, not the beginning/end of the current line. As someone who uses those keys a lot in Windows, that behavior is aggravating. There IS a way to change this, but it's very non-obvious, and doesn't work in all programs.
- Muscle memory of using CTRL+X/C/V to cut/copy/paste will screw you up as a Mac uses their Command key which is where Alt is on a PC keyboard.
- Finder sucks. You can't cut/paste a file to move it, but you can copy/paste a file to copy it. To move a file in the Finder, you have to open two windows and drag it. The Delete key doesn't delete files.
Often times, things feel different just for the sake of being different and not because the designer thought it could actually improve UI/UX. Apple seems to very much tend to subscribe to the mentality that removing features is a feature.
I recently started a new job and opted for a mac thinking "it's a unixy system, so it'll be more like my home linux setup". I have some regrets. The forced scroll acceleration is particularly intolerable; I had to find LinearMouse to get rid of that.
Another infuriating weirdness is window focus. Alt(sorry, _command_)-tabbing to a window brings all windows of that application to the front, possibly obscuring other windows you have around. And if you switch virtual desktops to one with a fullscreen window while you have another window of that application open on another monitor, it won't focus the fullscreen one you just switched to but rather the other window.
You can actually cut/paste in finder - just little different. You copy a file with Cmd+C, then paste it somewhere with Cmd+Option+V (instead of usual Cmd+V) and voila you have cut the file.
