Shrug, that is the popular perception, and they're all frequently referred to interchangably as "small ball" and "NL style." I'm not sure if you're just screwing with me or what, but I can't believe you would debate that.
It's only a popular perception for those who want to sound lofty by lauding the "virtues of NL baseball". while there are differences, they aren't as frequently seen as some people like to think. There may have been a little more of it witnessed in the 70's and 80's but not as much anymore.
