If you guys want to share your thoughts:
Well I don’t have a membership for twitter, so I can’t respond directly. but will post my thoughts here.
Four years ago I looked at BJS, 3Js and Blend4Web. BJS won out because of the well organized professional help, ease of use for a non-coder, and the friendly folks. Blend4Web I found slow and I found the Blender exporter created by @Deltakosh and @JCPalmer so easy to use.
Interestingly, there seems to have been issues at Blend4Web - as some people have been fired and those people have set a new company - Verge3D that costs money.
