LTSC is cleaner out of the box and has much longer support, but otherwise it's not that different. And Edge on LTSC still does annoying things, such as adding a Bing search box on the desktop, for example.
Checking with MS, unless you’re a registered developer or enterprise customer, you can’t purchase it. LTSC keys aren’t supposed to be sold by the single, so any reseller doing that is breaking MS’s terms.
