The criticism on the tooling seems excessive for the benefits it provides. On one hand you don't spend the time equally on the terminal, the text editor, dev tools and the platform's IDE. You'll normally spend most of your time in the text editor and the emulator. You'll have to use the other tools here and there, but in exchange most of your code will be shared across platforms.

Regarding code organization, I found redux to be a well established tool with clear patterns.
