I'm about 150 pages in and don't like it all that much. It's like it wants to be The Martian but just isn't up to the caliber. The only other book of his I've read is Snow Crash and it wasn't that great either, I don't think I'm much of a fan of Neal Stephenson.
The concept was fun, but I was definitely not a big fan of Snow Crash as a demonstration of writing talent.
Now, Cryptonomicon - if you can't get into that book, then Stephenson is definitely not for you.
Anathem is another very good read from him, but Cryptonomicon is far more approachable. Anathem's focus and slow start can definitely bore some people, Stephenson loves detailing... details... and the subject may not be attention-grabbing at the get-go, but I feel it really gets moving and the overall novel is very enjoyable and wraps up, while rather strangely based on the start, in a fulfilling manner.
Cryptonomicon, if you are interesting in war, cryptography, and digital currency, will quite likely grab you from the start.
Reamde is a fun read, and is a return to the world of digital security, hacking/viruses, and also features a contemporary MMO, but ultimately is mostly a story of a chase/rescue with those elements as plot-movers.
With that in mind, it's a fun contemporary read, but if you are looking for the most cerebral or intelligent novel with award-winning prose, it's not for you.
Frankly, Stephenson probably doesn't fit that frame of reference at all, but I don't want to sell him short, not everyone is destined to be a literary master that is referenced for hundreds of years. I like his contemporary stories, they grab me, and I suspect I should at least enjoy reading Seveneves, but I recognize that Cryptonomicon is an incredibly high bar to clear.
I myself wasn't particularly thrilled with the Baroque Cycle novels, they grabbed me in some ways, mainly because Enoch is such a fantastically compelling character, but I never finished the series because it was just too much messing around with ancient science and not enough compelling plot drivers IMHO.
