There are many but I tend to like SciFi, AI, Cyberpunk, etc.. I read a bit of LitRPG for random amusement and for something braindead when I am in the mood. I don't think I have a favorite of that though. I could dig through a few and give a suggestion or two if anyone is interested.
The two series I like (I have posted many times before).
- The Singularity series by William Hertling (first book is Avogadro Corp).
- The Daemon Series by Daniel Suarez (First book is "Daemon" the 2nd is "Freedom (TM)".)
Otherwise I just read anything and everything. I am sure my posting shows that for the most part.
