I agree with you overall, but it's remember that it's easier to be consistent across a smaller sample set and shorter span of albums. Rabin's band only put out three albums, the first in 1983 and the last in 1994, a relatively short period in the band's history.
It was 25 years between Close to the Edge and "crack time", during which time Jon Anderson's writing style had changed considerably. Yeah, "crack time" is cringeworthy, but there are people who generally prefer Jon's more literal lyrics as opposed to "a seasoned witch could call you from the depths of your disgrace and rearrange your liver to the solid mental grace" which is pure gibberish. Jon himself admits that the early lyrics were a mix of poetry, trying to create imagery which got the point across, and just throwing together syllables which fit and sounded good.
With over 20 albums across a history now nearing 50 years, I accept the relative low points if it means we get the highs. Nothing in the Rabin years IMO comes close to "Awaken" or "Close to the Edge". The Rabin years are very consistent, very good, but they also all sound the same to me. Every time I put on Big Generator or Talk, in an honest attempt to become more familiar with them and hopefully appreciate them more, there are at least a few times during each album that I realize that I haven't been listening at all, and have no idea how long I'm been daydreaming. It doesn't grab me and hold my attention. At least 90125 has some variety. To me, it's similar to what happened with Boston. The first album is incredible, groundbreaking, solid cover to cover. Then the second album came out and sounded exactly the same and broke no new ground. Then the third album also sounded exactly the same and broke new no ground. I tried getting into them, but the same thing happened. I found myself daydreaming, bored with what was playing, because it was all the same. Great sound, great songs, and still somehow boring overall.
