Ask HN: Express vs. Loopback. Want a real review for my next startup

Hey we are starting to create this application for our startup and this is going to be our MVP. So the stack we were going through was Node(Express) + Angular + SQL. The problem arises when we start looking for ORM for Express - SQL. And then developing Authentication , Authorisation Module and then comes API's. Suddenly we found this miracle baby the solution of everything Loopback. But then i realize nobody in our team has worked on it. We are ready to learn for sake of development but we want to be sure that it is what they are saying it is. So if anyone has any knowledge regarding Loopback and Express in production feel free to express his/her views. You are providing a lot of values in our life so thanks for it already.
