I’ve been through Three, Blend4web, aframe and verge3d. Babylon is the mot full featured and powerful for what I needed and it’s a pleasure to work with. Also forced me across to typescript which is a huge blessing.

Tried babylonjs week ago when they released new version. It was my first experience with 3D in the browser. But must say was very positive. I was able to do everything I wanted. The only bad was the lights shines through solid objects, so modeled room lamp is visible from the outside of the building :).

I didn't tried threejs though. So sorry for being bit of topic.
