Earlier quoted context omitted.
I just took a look at Titanium and holy moley their documentation was overwhelming. I haven't used a "native" hybrid app framework yet (only have experience with ionic), but NativeScript looks a bit more accessible to me than Titanium does.
I say the documentation is pretty ok once you get familiar with how the API is laid out. And for everything else they have the developer QA section, which is like a self-hosted stack-overflow. I've been building a couple of simple apps on it the last few months, and it has been a pleasure. I should be clear here -- I've been using Titanium, not Alloy.
I'm still new to the hybrid app world and have only used ionic. I want to eventually try one of these "native" frameworks though.
