I would tell you to use the language and tools which you and your team are most familiar with and/or want to learn. Just know that the latter will probably increase the amount of time it takes to complete the project.
Having said that the rave these days is using node with a NoSQL database and front-end driven by a JavaScript framework ie. MEAN stack. Though you could just as easily build this with php, ruby, python, .NET, etc.
The thing I don’t really like about the MEAN stack though it all projects become 2. You have one project which focuses on providing the server-side API and another for the front-end that consumes that API. This can work to your advantage though with a well-rounded team where one part focuses on building the server-side API and another the front-end.
