I always go with the stack that I'm most comfortable with, unless I'm using an existing stack at a company I'm working for. Learning a new stack because it's "popular" is a recipe for disaster if you're incorporating into a product you want to use or want to charge others to use. You'll spend time trying to figure out how to do things that you already know how to do in another stack.

Any stack will get the job done. Use the one that yields you a shippable product in the end.

My stack is ExpressJS, AngularJS, PostgreSQL, NGINX, DigitalOcean, Route53, PM2. And I fly through it.
