I reviewed these sort of web frameworks some time ago and went with ASP.NET Core because of the language attached being more to my liking and industrial-strength than Python, PHP or Ruby. I go in assuming every project will be 500KLOC someday, because it can happen. I've seen codebases this large in Python, and it was no bueno. Static typing, forward migration / backwards compatibility take top priority for me.
Laravel was my 2nd choice, the recent adoption of a JIT into the core really adds some desirability to the space. Not to mention HHVM and how much Wordpress is out there.
