Black Sabbath are the fathers of heavy metal and hard rock, I think they must have had a bad promoter (compared to LedZep) and the fact that they'd play just 1h compared to Zeppelin 4h marathons also made them less relevant in the grapevine

Turns out there's a lot to this. Read Black Sabbath's Wikipedia entry. As a band, they were always a total mess, with bad management, lack of discipline, loads of wasted money and opportunity, and also a massive amount of turnover among the band members. It's almost a miracle that they were able to create what fans now think of classic rock albums, like Paranoid and Master of Reality.
Led Zeppelin, OTOH, was conceptually very strong, determined, and ambitious. They not only had the toughest, best and most protective businessman among rock managers (Peter Grant), they were like a well-oiled machine where each member was firing on all cyclinders and they were greater than the sum of the parts. Jimmy Page specifically conceived the band to not be like the Yardbirds where it was run by a bunch of mafia guys and producers and had a lot of turnover. That's why when Bonham died, the concept could not work with one guy not in the equation anymore.
Led Zeppelin are just different. They are just on the right side of musical for me. I really can't stand dissonance or noise in music. I also greatly appreciate dynamic range which they have an abundance.
