brownies and choc chip cookies

I'm curious if people can tell the difference between boxed brownies and cc cookies? I ask bec this commercial kitchen I rent only sells boxed stuff (Pillsbury/Ghiradelli). I can tell the difference but I'm a foodie. This place I rent has sooooooooooooo many catering orders. I assume they do it bec it's easier but to me nothing like a homemade cookie esp when your catering.

Thanks!
