I used to use Intel XDK but randomly it would export a bad version of my game that would lag on some devices. And I also ran into issues with getting some plugins to work. Cocoon we view+ used to work great, but then I switched to canvas for iOS when they were having issues. Coocon puts out a fast performing game, but sometimes the server is down or has other issues. Nothing is perfect, but so far I've had a better experience with Cocoon.
