No matter how good you are now, your code when you've spent a year with a framework will be better. Consequently you should pick a framework (or language, or tool) and stick with it until you actually have a good reason to move on to something else. The benefits of jumping to whatever someone else recommends because they claim their choice is better for X, Y and Z reasons are likely less than the benefit of your own experience with a framework you've learned and understand.

90% of the speed of your code in terms of both writing and execution are a function of how well you write it, not the libraries you're using. Writing better code comes from practising (and thinking).
