We're talking Zepplin vs Sabbath here. Jones and Bonham kill Ward and Butler (easily) on the skill level. Ozzie was and still is an average singer (Plant kills him)..and you don't even want to get into an Iommi vs Page debate. When people talk of guitar Gods they talk Page, Clapton, Hendrix, Van Halen, even Blackmore on occasion. Never Iommi. There's a reason for that..
More specifically, we're talking about which band has a greater influence on the current music scene. That's clearly Sabbath, even though I agree regarding Page and Bonham both.
As for the list posted above, many of them have a much clearer Sabbath influence in their sound. I'm not talking about who they say has influenced them, that could be anyone who inspired them to get into music in the first place, and for people who were coming on the scene in the 1970s and since then, I suspect many would list Zeppelin.
I'm talking about influence in terms of the sound being reflected in the current music. Sabbath spawned an entire sub-genre of metal, and if I wanted to cut and paste as done above, I could paste a hundred or more bands that have this sound. Even bands that aren't in the subgenre reflect far more the sound of Sabbath than Zeppelin.
Many of the bands cut and pasted above are also older bands, and we were talking about the current crop of music - early 1990s and forward I believe. At least that was mentioned a few times back.
Many of the rest of those mentioned have no Zeppeling influence in terms of sound, even if they state Zeppelin was a personal influence.
As I said, I'm talking about how the sound influenced the current sound. You'll find a lot more influence of Sabbath SOUND than you will of Zeppelin, at least in the last 10-15 years worth of rock/hard rock/metal.
