Some time ago I needed some 3d on web so I did simple rotating textured cube demo and out of 30 webgl libraries tested only 2 achieved 60fps for such a simple demo. On web you have no performance to spare so when you plan on making larger project test performance first. If it's slow with simple stuff, it's only get worse as you add more and more stuff. (Sorry I don't remember which 2 were fastest, you should do your own tests anyway because when you will be writing your rotating cube demo you will read their documentation, maybe even posts on their community forums and you'll learn how good is doc and how friendly is the community)
