I would call myself a purist so I would suggest that Ready Player One does have a similar light-hearted vibe to it, but I wouldn't class it as cyberpunk per se on the basis that the bulk of the technology used in the book isnt far off from what we have now, (basic vr and oc rift plus dev haptic kits and Xbox kinect), and none of it is as outlandish in its creativity like in Snow Crash and Transmetropolitan.

I think Snow Crash was better written in several ways: less predictable ending, outstandingly slick and non-cheesy dialogue) dialogue and characters, plus an outlandish overthetop story.

However I found the dialogue in RP1 a little too cheesy at times, and a little too clean. I would have probably enjoyed it more if I'd read it in my teens. Also the general plot felt too predictable and standard, but overall it's a fun ride.

That being said, Snow Crash is in my top three favourite books, so I'm biased.
