Reddits new design is kind of a hybrid. It is MPA when you hop between subreddits and other pages. But it shows a post on the same page when you click on it in a subreddit feed. I actually are annoyed by the new Reddit enough to switch to old.reddit.com most of the time when I end up on Reddit. Not sure why. But maybe it tells something, that the only "somewhat SPA" I know makes me switch to its MPA version regularly.
All sites I use regularly are MPAs:
Hackernews, Amazon, AirBnB, Booking.com, Wikipedia, GithHub ...
