I'd say the core difference for those migrating is that they evolved with different 'evolutionary pressures'. Broadly speaking there's equivalent functionality for a lot of things, but windows has a lot of GUI while linux has a lot of config files and terminal commands to accomplish things.
Where I think the friction is the distance between new migrants coming to linux with glowing advertisements of it mostly being a drop-in replacement for windows but the GUI not offering everything, and crucially not hinting where to go to find things, so people head off to do web searches and play the lottery of if they get good/recent information appropriate to the distro and version they chose. Linux seems to be polarized between great for simple use cases (browser, gaming within the steam walled garden, etc) and those willing/able to dive into the terminal, but between those can be a wide gulf which is hard to cross.
