I disagree. I felt like Wallace used many more $10 words and the annotations were often long enough I would lose track.
Gravity’s Rainbow had easier text to read but I’d agree the narrative is probably more difficult to follow. I also think Gravity’s Rainbow is the better book in many ways especially as it rebates to “them” co-opting everything useful.
The chapter detailing Pokler’s history is probably the finest literature I’ve read.
