I've read all three but in terms of quality Ready Player One shouldn't be mentioned in the same breath as Neuromancer or Snow Crash. Those two was genre defining unique originals that were a departure from sci-fi of that time. Ready Player One was a list of movies the author enjoyed. It can be a funny, silly, relaxing read if you just want junk food, but it's not really comparable to the others.

I read Neuromancer when it came out, in the 80's. It was mindblowing. My parents had just bought our first microwave around then, the cordless phone in the house was like a huge walky talky, I was a huge nerd because I had a Commodore 64...

I tried Ready Player One, but I struggled to get into it, and it's actually what got me on to Snow Crash in the first place

Could not stand Neuromancer. I think it’s historically important for really inventing the cyberpunk genre. But the story is cocaine riddled and most of the characters are flat.
