It's something that I've said of many Tool fans for a long time now... The ones that think everything Tool has done is amazing really just haven't tried looking very hard for other music they might like. Maybe they listen to the other bands that Blair mentions on the Tool news letter, or bands that have opened for Tool, or bands that Adam has mentioned in an interview, or etc etc., but they're all connected to Tool somehow, who is up on a pedestal above literally everything else.
Lateralus and Ænima were 9/10 or 10/10 for sure depending on your personal judgment scale. I'm enough of a Tool fan that I would adamantaly argue that 9 or 10/10 as being a fact rather than an opinion. But it's just those two. Idk how to put into words what they tapped into after Undertow but they lost it up their own ass by the time 10,000 Days came out. If you think they're amazing then you really must not have looked very far for better stuff. And now this album too. (I know it's ironic since they opened for Tool and have been mentioned in many interviews, but if you dig the guitar+bass interlocking/interplay on this new album then check out the 80s-90s-00s King Crimson stuff, particularly 90s and 00s. Adam really did gank a lot of his style from Robert Fripp.)
Oh and even those 90s and 00s King Vrimson albums are just pretty decent, in reality they are all about their live show. Which I suppose you could probably argue about Tool despite their recent two albums being less than stellar. Tool's live show is still pretty amazing, and yeah live performance might be the true purpose of the band rather than studio albums. Hearing some of these songs evolve out of jams and random little guitar melodies Adam would play between songs over the years from their live shows was pretty damn cool. I should get back into Tool bootlegs, I used to spend all my time in the early 00s in the Tool DC++ chat room (think IRC with file sharing built in, really ahead of it's time stuff). I've made sure to listen to a bootleg or two from each tour for the last decade or so, but I haven't done a deep dive. Hmmmmm....
Please excuse my stream of consciousness ramblings, thank you
