It is campy and frequently cheesy, and I think probably influenced somewhat by anime which was in the 80s and early 90s both very different from what it is now, and still in the US a very niche sort of taste in that you had to be somewhat "plugged in" even to have heard about it - it wouldn't hit more widely until the mid- to late-90s Web boom made awareness and access much more broadly available.

That's part of the fun in my view, but it's equally fair just not to like it - de gustibus etc. Or maybe it's just a timing thing; I first read it when I was young and it was new, and maybe that has as much to do as anything with why I liked it so well and still regard it fondly.

Snow Crash was apparently originally envisioned as a graphic novel, hence the tone

I always read Snow Crash as a bit of a parody. Over the top, but in a fun way. It's definitely not a serious novel like Neuromancer is.

It felt like a hyperactive 14 year old’s anime fanfiction.

Fun for five pages, but when that tone keeps going, my brain just ends up feeling burnt out.

My feeling exactly. I don't get why adults would like this book.

it does not, it's a shit book. Diamond Age is better though.

I don't think you're an outlier really. IMHO the problem with Snow Crash is that it hasn't aged well. I enjoyed it in the mid-90s, but I recently re-read it, and found it hard to get through (until the very end, anyway). It feels like a frozen-in-time product of the early 90s in a lot of ways, not just in terms of the technological outlook but also with respect to some of the social aspects addressed in the book. There's also very little character development; at one point, for example, a character kills another character in a bar over a threat, and at no point later on does he experience any kind of mental or moral anguish over his first experience of killing.)

Neuromancer on the other hand has aged incredibly well. The ICE tech doesn't make much sense, but the characters feel honest and real, and so many actual contemporary issues (AI ethics, transhumanism, transgender issues, mass surveillance, anonymous coordinated activism, economic oligarchs heading into space, even a tank war in Europe!) resonate throughout the book in ways that don't feel dated.

Neuromancer was never really about technology according to the author, and that is probably why it feels the same.

Ironically although, I had a hard time reading Neuromancer while snow crash was a breezy fun read in high school
