Improvisors of Columbus: should I do classes at the Nest Theatre or Hashtag Comedy?

I’ve always wanted to do improv classes, and I’m happy that we have two places in town to choose from, but I also want to make sure I make the right choice for me. Is there a difference in teaching style, culture, or mindset about improv between these two theatres? I know some places focus more on game, and others focus more on character driving the story of a scene. Is it similar between these theatres?
