Babylon provides a playground where you can explore examples and play with the code.
The official documentation offers a wide variety of well-written tutorials on topics from beginner to advanced.
Additionally, there are many tutorials written by the community available that you can find by doing a google search.
Pro Great base shader material
Pro Actively developed
Babylon has great project health, with activity on Github daily for bug fixes and new features.
Con Editor is Windows only
Since version 1.7, Linux can be targeted for runtime. The editor for the engine is available only to Windows though.
Con Install & build very dependent on specific versions of MSBuild
Install and project building are very dependent on specific and exacting versions of MSBuild.
The problem, of course, is that MSFT update Visual Studio quite a bit and even slight version number differences (for example installing now versus a week ago) seem to cause install and/or project build issues.
Con No user community
Unity and UE have a vast amount of user community.
Xenko does not.
Con Iteration may be slower than with other engines due to longer "build" times when certain changes are made
Con Documentation has not been updated
It is being updated since October, 2016 and if coming along fast.
Con Young project
Babylon is quite young compared to many of it's competitors (released in 2013). The community is still somewhat small, however growing quickly.
