I've tried multiple visual editors that offer HTML5 and Native (eg Stencyl, MMF2.5, Godot etc.) and I find that none of them do everything well.
Stencyl is hardly a product that provides a fair comparison.
It's like taking a Lamborghini, comparing it to a Datson 720, and then proclaiming the Lam to be the best sport's car ever.
A fair evaluation is judging the product against it's true competitors (Gamemaker, etc).
(FTR: Both YOYO Games and their product is too unfriendly for my liking)
