Just adding my two cents, I know this thread is kinda old, but I have to say Cooonio in my opinion is way better than xdk. (I’m not bashing XDK. Its just my experience)
I’m about to release my next game on google play (just need to get leader boards working properly) and it’s been a great experience overall.
Highlights to me are:
Performance is great. I test on a galaxy tab 3 and a Samsung s4. These devices are fairly old now so I feel if cocoon apps run good on these devices they will run fairly well across the board.
On XDK my phone heats up a lot, this does not happen to me on cocoonio canvas+
I find on XDK that when ads load in my game it affects gameplay speed.
In cocoon the experience stays smooth
My entire game is 11MB which is not bad at all and that includes having cocoon google game services and admob ads.
My XDK games are 25MB+ (I create small games in general for android)
Ease of use
Once you get to know the site, setting everything up is actually easy to do and works well.
I’m struggling with leaderboards a little, but that’s just because its new to me. Once you know how these thing work setting it up will be a breeze I’m sure.
I’m definitely sticking with cocoon for now and do recommend it for your mobile projects.
Only thing I found out the hard way is that letterbox scale does not work in cocoon (or XDK) oops. Keep that in mind and design your game accordingly
