I Voted no... I have worked for both petco and petsmart 3+ yrs at each. I enjoyed working for petsmart much more tbh. and Though I will on occasion still buy a fish from them or petco I do not like a few things.
A) their tanks are one giant system. If one tank has Ick. Every tank in that system has Ick theoretically.
B) Lack of employee training. Unless the employee is a dedicated hobbyist themselves, your better off asking them about dog food.
C) They routinely stock Bala Sharks, Pacus, Oscars, and other Monster worthy fish imo that are NOT beginner friendly.
I can not tell you how many times I had a customer come it w/ a dead goldfish in a bowl that some idiot co-worker told them "it was perfect!" But I will also say the rare few you find who work in these chains and truely do enjoy their hobby can be a gold mine of info. My manager at petsmart worked in the pet industry for 20yrs prior to her management posistion at the store. I learned more about animals from her then from any book.
It's all about who's running the store, not it's name.
