The really big one for me is installing things. Installing packages requires 0 interaction, can be easily automated, wide availability of packages, etc. On Windows, Winget sucks. It's just running the regular installers. MacOS is better since it has Homebrew, but it has some problems. Homebrew struggles to update "casks" (aka GUI apps) so you still have to rely on app's in-app updaters. MacOS's gatekeeper also is annoying about third part software. And for anything not in Homebrew, you have to install it from the web.

Programming is also easiest in Linux. MacOS is a pain sometimes. The preinstalled toolchains are outdated. Installing new ones from homebrew also requires reading through a large block of text in order to find out what manual steps you need to do.
