I must say you wrote that well and I agree with many things in it. But the music and the role of the drums is important as well.
These comments are important when we compare Maiden and Bruce's solo music:

Bruce's solo material has amazing vocal and guitar work, but the rhythm section is steady at best, kinda basic and gets the job done. Whenever I listen to CW or AOB, i'm always thinking how much better they'd be with Steve's throbbing bass lines and Nicko's manic, over the top drumming.

To my ears it's clear who the songwriters in the respective bands are. Maiden is very rhythmically interesting and varied and you can hear that Steve is the main songwriter.
On the other hand, Bruce's solo stuff is (and deservedly so) a bit more vocal and riff centric as they are collaborations between Bruce and a guitarist (Roy Z for the most part).
Yes. Bruce's stuff is built around guitar riffs, so the guitars are more prominent, or have more freedom (I remember that Steve once said that H complained in the past that the guitars have not as much freedom in Maiden), and the rhythm section "plays along". I even think that on TCW the bass was recorded after the guitars. This guitar orientated style, that happens often in metal, look at Priest e.g., and countless of other bands.
On the other hand we have Maiden who are one of the minority category bands in hardrock/metal where the rhythm section has the leading role. So both of these styles of music should be seen in their own perspective. Nicko's drumming is more prominent because he has an important "matching" role with 'Arry's bass. In Rush it's the same. Peart doesn't get credits for the music in Rush, but he surely composes his highly interesting patterns, which are very dependent on Geddy Lee's stimulating bass lines. With all respect to Lifeson, I also think Rush is a rhythm section band, where (especially in the eighties) the guitar plays a less prominent role.
Back the Bruce. This music indeed needs a stable drummer, one who can play tight in constant mode. This might sound less exciting but therefore it isn't way easier. The drummer has to drive the rest of the band in this kind of music. Nicko can do that too, but often he varies (indeed you can't predict what he does) and this wouldn't fit to this kind of music, I think. Besides, in live situations Nicko is known for making mistakes now and then, so in that perspective he isn't one of the most stable drummers.
What I try to explain (also in earlier posts) is that the styles of metal are different, each need their own qualities.
I also find Maiden's style, and Nicko's style more special, but I wouldn't say that the other category is b-rate. It's different and more demanding on other aspects.
