Pros of CocoonJS:
1. You can publish to multiple platforms at once. (Android, iOS, and Amazon, Chrome, and even Tizen and Ouya app stores, etc.)
2. It has the best performance of the any of the other mobile export options right now.
3. Low file sizes make games easier to install and less likely to be uninstalled.
4. Everything works and runs smoothly on mobile.
5. Ads and IAP work great!!!
I personally have had a great experience with it so far..
Can any of these other exporters really do the job????
