I'd suggest that two different darkroom workers would most likely produce a different result from the same negative (assuming that they didn't know one another's filter settings). Two labs certainly would, but each print could well look perfectly acceptable on its own.
As to comparison, you could certainly evaluate and compare prints with the correct measuring instruments (densitometers, etc.). Doesn't, of course, measure the most "pleasing" result, and the latter can also vary from one viewer to another depending on eyesight, vision and personal preferences.
Edge markings could be different, while the films might be the same....not saying that they are the same. For example, Agfa Vista plus
is obviously a Fuji-manufactured film in Agfa clothing. No problem with that, it works just fine.
