You mean canvas 2d? If you're making a 2d game, it's good enough and looks really nice. Performance is good enough in most cases. Because of some OpenGL gotchas in some drivers (macOS mostly), some operations are a lot slower in those OSes (I have a demo that runs at 3 fps on my macbook, and >144 fps on my windows). It's easier to use canvas 2d as you don't have to deal with any of that.
