Stratechery. I've been a subscriber since 2016.
In the last couple years Ben added a private podcast stream with audio versions of his newsletters, which has been a huge quality of life improvement for me. I wish more newsletters did this, I would happily pay more.
Keeping up on reading newsletters was fine when I used to travel a lot, but now (with kids, post-COVID) I generally just consume the audio version while driving, working out, etc.
