It seems, for this exact moment, to be:
-cocoonJS canvas+ for android (fast when it actually works, and while scirra depreciated it, ludei started right after to do things correctly so it is useable, more infos can be gathered around)
-cocoonJS webview+ for iOS8 (silverforce particularly seems to really use it and have not had issues with it)
Crosswalk is not fine at the moment due to bugs (which are said to be temporary, but since it is with the chromium engine itself, you can expect it to be quite problematic until it is fixed in chrome and then integrated to the current crosswalk), once they are fixed it should be really fine (aka like it was before being broken), but since I do not know your deadline requirement nor your exact project, I would say not yet worth it currently.
Phonegap is plain bad for android below 5.0, and with android 5.0, you have to expect the possibility that the webview may update and break your game one day.
My guess would be that if html5 is not something you care at all, and if performances are really important, you go onto another engine, at least that is how I feel about the situation, I mean sure there are always dependence on third party, but as far as html5 wrapper goes, there are far too many things to consider for them to not break completely in one update For a specific engine For now at least.
