I'm heavily biased in favor of the idiomatic style of the language I happen to be using. There's less context switching when interfacing with external libraries that are expected to follow the same. There isn't a significant loss in velocity in adapting to use one or the other or even simultaneously (front_end_javascript, BackEndJava, SELECT * FROM blah). The most significant portion of my time is spent thinking/designing/debugging; I save the balls-to-wall frantic keyboard banging for NCIS cameos.
