I agree OP. Basically, here is how it is:
Boruto manga chapters have about the same amount of progression as a Naruto chapter did (and Naruto wasn't really so fast paced in terms of progression), but Naruto could get away with it due to weekly releases. Boruto cannot get away with it due to monthly releases.
I've kept up with two other monthly mangas (DBS and To Love Ru Darkness) and they both do monthly releases a lot better than Boruto. Unlike with Boruto, both DBS and To Love Ru Darkness had at least something relatively significant happen in just about every chapter. There is almost always some form of progression. Boruto manga however allows for chapters where nothing really happens (like that chapter where they were just testing out the ninja tools). This, coupled with monthly release, makes for what seems like a manga that moves at a snail's pace. At least things are finally getting good though with KK, Karma seal, Kawaki, etc...
