Why use LTSC over, say, Pro? Genuinely curious. I have been running 16299 on Pro since about when it came out. I would be running win2k if drivers, etc were updated for it.
LTSC is designed for the most conservative of customers, who don't want ANY funny business on their operating systems.
It's technically possible to tweak pro such that it's mostly the same thing, but LTSC comes that way out of the box, fully supported by Microsoft, and that's not going to change because they don't want to lose these lucrative enterprise customers.
LTSC/LTSB doesn’t have the Windows App Store - and to my knowledge you can’t install it either. Pro cones with the App Store and to my knowledge you can’t uninstall it.
