> Like many others - I dropped Cordova and Ionic in favor of React-Native.

Few years ago PhoneGap apps were really slow and ugly. So I built native Android app. This year I started building hybrid Ionic 3 app because it has to work on Android and iOS. It works good enough on Nexus 5 (Snapdragon 800). The biggest problem is 4-5 seconds startup time. Stencil and component lazy loading should greatly reduce that startup time (to 1-2 seconds I hope).
