out of all classes in div. 1, which is most interesting and most competitive?

it is almost impossible to say. It would depend on your point of view. The larger cities are going to have more 4 and 5 A teams, while the more rural areas are going to have either 1 large county school or several small ones. (I'm just sterotyping, here). There is nothing like watching two small schools in neighboring towns go at. That is true high school sports. But sometimes when you watch some of the larger school go at, you can see a ton of really good athletes go at it in a bigger setting. I think this would all depend on which team you follow and where your loyalties lie.
