It's a little bit like asking which color you should like. A lot of main stream programming languages are very similar in capabilities but differ in some of the details on how they express this, i.e. the syntax. The programming languages you end up choosing probably has a lot to do with how appealing the language and the ecosystem around it is to you. You might want to try a few languages such as Python, Ruby, PHP, Javascript, etc. I would suggest to focus on the language first and then the frameworks.
