some things I've noticed: Mobil Safari seems to be using the search bar to hijack my google search (Particularly for locations which open in apple maps)
Although I'm mostly linux these days I went to install an alternative browser on a windows machine (using edge to download). I mentioned this in another post, but edge seems to watch for "chrome" or "firefox" downloads and politely reminds you that 'Edge is a great browser with added "trust of microsoft"' (A company who happen to be watching when you download a web browser).

Linux seems like an OS that is way more respectful.
Now you get the benefit of Windows power management (and that beautiful laptop battery life) but a web browser Microsoft isn't going to mess with.
This sounds hilarious were it not the way I actually work.
PS: I'll also mention that VSCode from Windows to WSL2 + Debian is a mind-blowingly wonderful thing, I don't know how it works but it's near magical as a dev environment when you need a full Linux but like having battery life.
Linux has never been this, and likely never will be. On any hardware supported fully by both, Windows will always have better battery life. Back when I was a thinkpad user, i'd literally live in a vmware workstation linux VM on windows, and THIS had better battery life than linux natively on the same thinkpad.
From the Thinkpads I have seen and used (last one in 2023) I haven't yet seen one that is "fully supported" out of the box on Linux and all of them required some degree of tinkering.
By the way Arch wiki has a nice overview on configuring power saving properly, in case you ever need it in the future: https://wiki.archlinux.org/title/Power_management
