Ultimately, there isn't anything that one server-side language can do that another can't. Each language will do things in its own way; but either can be used to achieve the same end result.
Beyond that, there is no reason to ask such a question without starting a flame-war.
We don't need to have another thread where proponents of one language start playing the "my language is better than your language" type of game. "Better/Easier/Faster"
is (for the most part) relative, subjective, and unquantifiable -- in other words, it becomes a matter of taste.
