It's about native api integration of mobile devices.
CocoonJS has the best fps and audio performance so far,
but it seems CocoonJS has only gamecenter(Googleplay serveice), camera, notification, Mopub and FB; furthermore, as a C2 user, in the long 2.5 years, we finally got gamecenter and Mopub worked correctly in recent 2 months. Thanks for androidtimo's back button and sergyperov's notification, and we can't access FB till now
We had ever paid much attention on IntelXDK since its name is Appmobi. With Tap's hard work, the IntelXDK had ever been the best solution with directcanvas speed, barcode, camera, fixed orientation and multi-thread audio. The device compatibility had been the superiority of IntelXDK than CocoonJS. However, what leftover of IntelXDK we got? Yes, the not-bad performance Crosswalk ANDROID ONLY.
Phonegap is the wrapper with worst performance for now, and you can't even make any tolerable commercial game without music; however, it has the most native-like app opening experience(IntelXDK and CocoonJS has a terrible 10 seconds wrapper opening time.), and we can see that in 2.5 years, with the improvement of mobile devices themself, the fps performance has 10 times increased.(In my case, 2fps to 30 fps)
It maybe a good chance, when iOS8 comes(Android should also do something reactive.), Phonegap exporter with plugins of native api integration may finally empower C2 mobile games technically upside with other game apps.
I respect the plugins what cranberrygame made for us no matter they're free, paid or donate-requested. Also, I won't regret for my donation or payment for them if there were anyone made free versions. Like what R0J0, Pode, rexrainbow, thehen, Lunarray and all the great plugin makers do, Phonegap plugins provide opportunities for C2 users to fight against other serious game engines
I think we desperately need more and more alternative mobile wrappers/services/plugins for C2 for commercial development. The diversity will make endeavoured C2 users more adaptable among increasing users of Unity, Stencyl, Salad, GM Studio and Unreal(Blueprint).
