The fantastic thing with Principle, when you mix it with an other app like Sketch is that:

1. You can concentrate your energy on design only on one side and prototype only on the other without "polluting" your main design file
2. I tried most of them and Principle still a fast, easy and cost effective way to achieve prototypes
3. Sketch + Principle : Lifetime Purchase ^{_^}

But at the end…I suggest you to try every solutions that you will receive and make your own idea on what's makes you more comfortable to work with!
