Something that I believe is dragging down “mass audience” sorts of distros like Zorin is that they’re only Windows-like in a vague sense, leaving them in an “uncanny valley” of sorts. One of these distros really needs to commit to the bit of Windows-like-ness so it’s a seamless drop-in to the greatest degree possible.
I don't know, when I installed a linux distro with xfce on her laptop after he hdd died it took my partner months to realize she wasn't using windows. I mean she only figured out libreoffice was installed instead of the pirated copy of office she used to run and complained the menus were different. Little she knew that a more recent version of Office would too have different menus/items placement anyway.
So there’s some number of users who could probably just be switched over by PC vendors preinstalling Linux, but there’s other groups who’d benefit from something more truly Windows-like.
Aside from those groups, I think there’s a crowd that could be attracted by simply selling your distro as being like “Windows when it was still good, except this time you get to keep it forever”. I think there’s a decent number of people who’ve become fatigued with modern Windows but don’t care enough to switch who’d be pushed over the edge by a distro that’s a near perfect reproduction of XP, 7, etc. Nostalgia can be a powerful motivator.
