There are really good web frameworks, both frontend and backend, out there. So, I would second the opinion that the best framework is the one you feel most productive with. However, I'd like to highlight ASP.net Core + Angular + Visual Studio here. Microsoft appeasement towards Open Source and cross-platform made this a solid choice. As web apps grow steadily in complexity, a modern strongly typed language like C# (and TypeScript) might be helpful for architectural patterns. And, last but not least, the tooling around the Visual Studio product family is maybe best in class. I am saying all this as someone who has not touched any Microsoft product for years.
