My guess (and it's only a guess) is that the amateur films - Kodak Gold and its Fuji equivalent) Are probably more tolerant to mis-processing than the professional films. But it may not be by much. The amateur films are designed for a certain amount of environmental abuse (high storage temperature, long latent image storage, and the like) and for processing in many, many small labs which may or may not use the quality control tools correctly. A lot of attention was paid to making these films work right under just about any circumstances. With the professional films the attitude has been that the user is responsible for doing things right.
