For a full-stack app or just simple APIs I'd go 100% with Laravel. You get a clean architecture, beautiful documentation and friendly and always growing community: the project is yours, from A to Z. With their docs and resources like Laracast you can start from zero and build what you want, when you want. The learning curve is definitely smaller when compared to Symfony and, with the help of a bit of "magic" (Facades etc.) you get the same results in the half of the time with cleaner code.
