naruto had one overarching plot
Boruto kinda just does whatever
First it was shin uchiha then momoshiki and then kara
all groups that have nothing to do with each other and even if they didt, there's no connection between these arcs beyond the same characters being involved
and with naruto
each arc connected
chunnin exams lead into directly into the search for tsunade arc as they need to fetch her to fix sasuke after itachi messed him up
You must be registered for see links
and even after that point, sasuke went to join orochimaru cause of how he was having no chances at getting revenge with his constant failure and then as you know that whole thing started the sasuke retrieval mission
which followed into shippuden with naruto's motive throughout that series trying to rescue sasuke
comparing boruto to naruto
is like comparing a trash bin to a gold bar
