I find that claim dubious, but at any rate you're forgetting ...And Justice for All and the Black Album. Both of those were very distinctive from the previous material.
I said they're some of the most important extreme metal albums, not the most important ones. From a perspective of being innovative and influential, they are some of the most important. Read my post next time, dude.
Oops, sorry that I forgot the lesser version of Master of Puppets and the album where their sound became a lot less unique and much more simplistic. My bad. Even Painkiller, which was extremely different from earlier Judas Priest although it's also overrated, was a bigger evolution than either of those albums.
Metallica had 7 demos and an LP floating around California before Slayer had released Show No Mercy. Metallica was on the first Metal Massacre while Slayer didn't catch Slagels ear till the third one. They were also performing originals that would later appear on Kill Em All while the dudes in Slayer were still doing Maiden and Priest covers. I agree with you, in that Slayer deserves more credit than Metallica for death metal influence/innovation - but certainly not thrash.Slayer was much more influential both on thrash metal and also on extreme metal than Metallica, with Hell Awaits and Reign in Blood being by far two of the most important albums in extreme metal and a clear cornerstone for the evolution of death metal.
Judas Priest is the most directly influential metal band aside from Black Sabbath. It's blatantly obvious that they not only influenced Iron Maiden, Metallica, Slayer, and every other heavy/thrash/power metal band, but they're also clearly the catalyst for metal to strip away the blues influence of Black Sabbath and become much faster and distinctive as a genre separate from rock music.

In the grand scheme of things, Metallica probably played more of a role in influencing the mainstream popularity metal than they did in influencing entire genres.
The difference in musical style between Sad Wings of Destiny and Stained Class is much greater than the difference between Kill 'em All and Master of Puppets

That's a tolerable opinion if you're talking about their first 4 albums.
I am talking about all of Priest vs all of Sabbath, including thebad albums by both. One solo alone on Painkiller > Sabbath.
