part12studios I only used the cocoon ads and cocoon share plugins. Right now I have no need for IAP plugins and all that. But the experience has been WAY BETTER than xdk.
I use admob ads for banner and interstitials. You also can use third party plugins and install them to cocoon such as a cranberry plugin. I know cranberry has some rewarded video plugins so you can use those.
No problems at all with screen lock and status bar does not show when you put it in full screen (unlike xdk).
The downside to cocoon is the $500 splash screen removal for each project so if you care about that it would be an issue. You can however request to have a premium type of account where you basically get everything for free. More info here https://cocoon.io/pricing
Overall, I would say you get what you pay for. Construct 2 to me is the cheapest to make games compared to GameSalad, Stencyl, Unity, Buildbox, (all these basically have their own exporter) etc. But with C2 it's basically learning another big step to export.
