three.js seems to be more well known/established than babylon and I had initially picked that for playing around. However, I got to go to a session on babylon at a microsoft conference and it was given by one of the authors and was pretty impressed. I had a freelance contract that needed some webgl and went with babylon and i'm glad i did. It better performance and the object names and concepts seemed easier to follow and a little less obtuse. IIRC, the presenter said that they are extremely diligent about working through bugs and issues on github and that three.js had quite the backlog. It helps that babylon is essentially being underwritten/subsidized by MS, where as three.js is more your typical open source project. If you've invested tons of time working in three.js, then it may not be worth switching over. But if you're dabbling, it is definitely worth checking out. However, all of this was about 2 years ago, and you never know what has changed.
