Right now your focus should be get a MVP out. Don't worry about the technology. You can change the underlying tech later once you have a viable business. Pick something which you are comfortable and get the product out
The problem I have is that I am comfortable using either, but can't really understand the long-term implication of my choice. Obviously I can change the tech later, but with it being money I see the switching cost being much larger than normal. It's about wanting to minimize risk now as much as possible with view to future development on the platform.
