If you're going to pirate, might as well pirate Windows Server, which is basically the same kernel with a far less offensive (and bloated) userland configuration.
I'm not sure, I've not tried LTSC --- but the fact that I've met a few Microsoft employees who run the Server version on their company desktops and even laptops (because as an employee, they can get legit licenses for basically free) speaks volumes about what they think of Win10...
But I have never run Windows Server
