If you have not already done so, I would recommend choosing a language to invest in, with the goal of becoming proficient in it. The purpose here is to select a language to be your "default" language. Write out a list of the things you value the most in a language and the things you wish to avoid. Examine the languages/paradigms you have already learned. Do any of these meet the criteria you listed (pros/cons)? If so, pick one of these to learn at a deeper level. If none of these are satisfactory, spend some time researching other languages or paradigms. Do other languages/paradigms match your criteria more closely? If so, it may be worth investing the time to learn something new.

I have yet to come across the "perfect" language or paradigm, but I have come across ones that have stretched me to learn new concepts I likely would not have learned otherwise.

One criteria I would not leave off the list is this: "I want to enjoy working with the language/paradigm."
