I don't know if it's of any help, but I offer my own experience:
I read Neuromancer as a teenager, and it had a profoundly transformative effect on my life (probably more than any other book). It first introduced me to the idea that a person like a hacker existed. That it was a viable thing to become. I may have discovered this at a later time on my own, but I'll never know.
I was so enraptured by the ideas contained in it, that I was able to look past what was mechanically, a style of writing that I really didn't like (the prose felt very disjointed).
When I moved on to Count Zero, I found that the story wasn't sufficiently enthralling to make up for the issues I had with the style, so I could never get through it.
About ten years later, somehow or another I came to find myself in possession of Gibson's Pattern Recognition (I don't remember if I bought it because of a good review, or just wanted to give him another shot).
For whatever reason, I found that I didn't have any of the issues with his style getting in the way for me. I don't know if his writing actually changed (a possibility, as it was his 7th novel), of if I was just a different person by that point, and now more able to appreciate the way he writes.
I ended up liking Pattern Recognition immensely (and both of the other novels in that trilogy), even though people have made valid complaints about the actual plot of the novels.
I then went back and re-read the rest of the Sprawl trilogy, and found it easier to digest this time.
So you might also find that his later work is less confusing.
I don't really have an opinion as to how it relates to SciFi as a whole, as I really don't like SciFi as a genre in and of itself (as a contrast, I actually hated Enders Game when I read it as a kid).
