My suggestion would to find a GM who works well with you stylistically. I share a lot of your sentiment about pacing (this is why I tend to run my own things). I also typically do plot things fast and furious, so conversation in some instances falls more to the backside and people are more about giving their reactions internally to the events unfolding. If there is commentary, it usually brisk given the dire-ness of the situation. I will say that while I usually find interaction boring, it has been pretty entertaining for me currently mostly due to the strangeness of some of the characters I'm with right now.
