Are you running version 1903, and if yes how overall satisfied are you?
I am running 1903 on a few machines. 1909 is supposed to be a very light "service pack" version neatly sorting only required updates while offering very little change from 1903.
1903 added some things that were useful, but broke more. Most were fixed in WU, by updating drivers, and installing updated versions of programs. I wouldn't want to do a fresh install from ISO without internet access.
One item I didn't like was MS requirement for Intel/AMD to remove display driver/program functionality and move it to a Windows Store app. 1903 also broke the Asus mb utility program. Not entirely satisfied to be perfectly honest.
