I agree. From the standpoint of what you can build a product using alone, any one of those is a good choice. However, I've learned that readability, along with being fun and efficient (from a developer productivity standpoint), is important, and the language makes a huge impact on all of these. I would argue that you can make say PHP readable, but it isn't necessarily going to be fun or efficient (but if someone can get all of those things, more power to them).
