Well, complaining about a mix doesn't necessarily mean it sucks or is objectively bad; there are a lot of cans of worms being opened with those questions, with tons of varying factors. For example, I'd argue that JP, talented as he is, has damaged his hearing from decades of playing extremely loud music night after night and hasn't produced a record as sonically pleasing as, say, Images & Words because he seems to lean heavily towards a sludgy, heavy guitar sound that overpowers the high end of DT's music. And most of the arguments I hear in favor of ADTOE's production don't really stack up against the criticisms I see. But, everyone's different. Not everybody focuses on the production, not everybody cares. I just know that even me, someone who is certainly not an audiophile, is baffled by a lot of the production on a lot of metal records specifically. Other genres I listen to more often than not have great production, but metal artists are always the ones that stick out like a sore thumb for one reason or another, the quality seesaws from artist to artist and even record to record
Also let's recall the story about Six Degrees' production where I believe they stayed up all night fidgeting with the production only for JP to go back on all of it the next day.
There's something to be said for working on something and being involved with all the little details, your ear sort of trains itself and what sounds good in the moment may not sound great the next day, or vice versa, or six months down the road... Audio is super tricky.
