macOS, with a combination of Bash, AppleScripts, and system-wide third-party utilities like Keyboard Maestro and LaunchBar, provides extraordinarily efficient ways to do powerful things, whereas doing anything on iPadOS is like being stuck in quicksand. Just the minutia of navigating the OS with only Apple's provided gestures is so slow and clumsy that I wouldn't bother to do anything complicated with it. It just takes so much effort, it's exhausting. So neither OS is great at discoverability, but only one OS can be used efficiently by a proficient user.
I'll say it again and again: The measure of a platform is not how easy it is to use for it's weakest users, it's what it's more proficient users are able to accomplish with it. Until Apple takes proficient users seriously, iPadOS will be nothing but a side dish, because no one will use it to make anything that anyone else would ever want to emulate.
