I cant speak for the others but a close friend of mine from Canada who runs a mainstream biz (weddings, portraiture etc, only uses primes unless absolutely necessary. I like using both but again, I am far from a pro
SDA does some really nice work imo, I would consider what he has to say. Even if the lenses are different he can prob advise ya on the prime vs zoom issue. I don't know fuck shit about bm bradleys work but i sure love his quotes. All joking aside, i'm sure his work is excellent as well.
Best of luck.
