What makes H!P cons these days interesting is the shuffling. You can just hear the audience's reaction when they hear the intro and see who get to sing it. It keeps things unpredictable. Let's say with Berryz con, I just know they're gonna perform most of the singles, and if it's summer, then Semi and Natsu Wakame and other songs like that. With MM, it'll be songs from their latest album plus a few popular classics... etc etc. H!P cons aren't like that. Okay, in summer con, they might sing Meccha Holiday, but then again... who gets to sing it? That's the fun in it. If I want to see an H!P act singing their own songs, I can just go to their concert.
And, yes, I prefer Berryz over anything in H!P right now. Coz 99.9% of everything they do is entertainment to me.
But no showing flesh, please. I'm not that kinda person.
