I don't know about NBA but in baseball the blaster box is the worst value of any of the retail products. It's the most expensive per card option so you are essentially paying extra $$$ for a , more often than not, useless 'hit'.
Blasters are the only retail item I have purchased of Prizm basketball so not sure how they stack up against the other retail products. I did manage to hit a SGA /25 in a 2018-19 Prizm blaster ( a bona fide hit) so with that experience I'd be more inclined to go for the Prizm blaster. Not sure if there is an exclusive hit for hanger packs?
