LTSC: What is it, and when should it be used?

You tell that preferred choice is changing in the industry? Any approximate numbers? Say a year ago 30% of enterprises preferred LTSC and today 25%?

I would love to stay on SAC, but with limited IT human resources, budget and time (like in most SMBs) it is too burdening to keep up. And what about "stability" flop of 1809? I doubt any serious org has started even testing and i feel 1903 will be released just after most update to the latest version. 2 updates per year is too often (i know i can skip, but what is the point then to use SAC anyway). We don't have money for Intune, SCCM, Enterprise versions. Dealing with feature updates via WSUS is PITA. Btw, is there x64 only feature update for 1809 in WSUS finally? A few weeks ago there was none. Why advertise new cool feature like 2 times smaller update size by splitting update into x86 and x64 and only providing packages for older versions?

I think LTSC believers won't disappear soon, as many may prefer stability (real stability) over theoretical improvements and possible problems. If anything, they numbers may grow after the 1809 blunder.
