It's a matter of personal preference, what kind of person you are and what music you play, there is no good and bad. If you are in a reggae band, you have to play behind the beat or it sounds like white-boy new wave reggae (The Police or Fischer-Z).
I once had a drummer in the band who was Bonham'esque behind the beat all the time. The guitarist loved him for it, but it drove me - weaned on Ian Paice's ever-so-slightly-ahead-of-the-beat swing - absolutely nuts. What sounded heavy to the others, sounded clumsy to me and I didn't like what it did to my bass playing either. And in my ears, Bonham/Jones as a rhythm section never - thanks Alan! -"drove the bus" like Paice/Glover (or Ward/Butler!) did. There was just more elegance in Purple's engine room, a track like Highway Star is fast, but there is nothing rushed or ham-fisted about it, it glides along. In contrast, when Zep play something a little faster like Rock'n'Roll or Immigrant Song, they invariably stomp (which a lot of people find appealing because it is so primal). Even a headbang number like Smoke On The Water never stomps.
But for a reason I never understood - Zep's enduring popularity must have something to do with it, the advent of disco in the late 70ies might have played a role too - behind the beat drumming became ever more popular in harder music from the 80ies onwards. A drummer once told me: "It's not that difficult to credibly ape some of the more overt things Bonham did, but that Paice swing thing is hard to get and you don't hear it that much in today's popular music anymore either, so people are just not used to and influenced by it." Paice says he heard big band music and Buddy Rich to death as a child as his father played in a big band in the 40ies and 50ies.
