Based on the strength of the brand alone, Focal wins hands down as the best speakers manufacturer compare to Alpine and Boston (as some of the series are even OEM from others). But what is your budget??? Different series yield different results and quality. As for your pointed favourite genre, I think any of the brands you listed should do well but place priority on those speakers that can produce very good mid bass. Lastly, make sure the speakers are powered adequately. For example, you don't power the Focal K2P with a 2x50w RMS amplifier as you are not giving them any justice.
