My experiences:
I have successfully published to Android and iOS.
Android: Crosswalk, Intel XDK. It's pretty simple to do that, except the file is too big.
iOS: Intel XDK (Scirra prefers PhoneGap, which is great, it's simple, you can test the built app quickly - by scanning a QR code, it installs to your device. But: when I tried to publish it to App Store, I received some random errors, missing icons and files etc. That's why I'm building with Intel XDK.). This one is complicated. Full screen, for example, doesn't work, you have to include plugins (File and StatusBar to XDK). It's hard to add all icons (you can add the ones in the Icons dialog, but then you get a Codrova icon in Settings, Spotlight Search, App Switcher). I hope I'll success with the next version. The main problem for me here is, that I can't test the app until I submit it to App Store. I receive an error "App Name could not be installed at this time".
I don't use any monetization at this time.
Also, I've published to my website as HTML5, and this one is incredibly simple.
