Crosswalk: Cocoonjs: Cocos2d: they all allow to use JS. Construct 2 support top two for now. But i haven't seen their performance compared anywhere nor their features. I think as game devs we need to know this, we need to know what's out there.
I would even take reasonable opinions too, if no benchmarks are available..
Can you list which has best speed, and some notable features or lack of them.
For one crosswalk only supports platform 4.x+ but has accelerated support for webgl.
