It kind of barely touches on FoundryVTT which is pretty much the best of the bunch if you are ok with running your own server:
-you own it
-you own the content
-lots of modules and very active development and support. Both official and fan based
-great to use for a number of systems from DND to Warhammer and too many to list on mobile
-very slick to use and macros allow you to do many cool things easily
I had read his post. There were plenty of other comments asking how/where and this makes it an easy option.
