The kind of camera jingoism we see today didn't really exist back then. Then, as now, there was no such thing as a BAD camera from a major manufacturer, but before the internet, the community of users for a given brand was small and local. So while people had their favorite and would discuss cameras endlessly; there just wasn't as much smug, self satisfied, assery that we see today.
Generally, the legendary brands that people talk about today were the brands people wanted back then.
35 mm? - Leica - any of them, Nikon F - Not so much for Image quality (thiugh that was very good) but for rugged reliability. Contax. Canon? While very good, it was just another 2nd tier manufacturer, along with Pentax, Topcon, and Minolta. Third tier? Cosina, Yasica, Mamiya, Pentacon (E German)
Medium format - Hasselblad, Rollie (TLRs - Slrs not so popular), Second Tier, Mamiya (TLRs, large format RFs), Bronica SLRs. Third tier, Yashica Mat, Minotla Autocord. (These weren't 3rd tier in quality, but they were ending their economic usefulness by the 1960s and their manufacturers were starting to concentrate on 35mm)
To me, third tier doesn't mean lower in quality, they were all pretty good, but they did have lower sales numbers, and weren't considered as 'cool' as the other brands.
