In most podcasts the value is in the information, not the timing. 2x speed is more enjoyable (or maybe a relaxing 1.5x speed if you don't feel like concentrating) because there's less boring waiting involved.
Even if it's a purely educational podcast or audiobook, any form of pacing or diction is lost at 2x, which, ironically, makes the story boring as well imo.
Sawbones is an edu-comedy podcast about medical history, and I tried listening to it faster and just didn't enjoy it as much. I really enjoy the comedic timing and interplay between the hosts, and it's already information rich enough that I feel fine listening to it at normal speed is fine.
One of the things I really like about WtNV is the almost menacing, deliberate pacing of the narrator. His speech is so perfectly even, regardless of the content, that it's almost hypnotic. I tried that at 1.25x and it felt off, but again it's a personal preference thing.
