Greenwald's the only for-sure other. Yascha Mounk also seems to have his head screwed on straight but isn't a journalist per se. I was hoping Isaac Saul was another diamond in the rough but he ended up going off the deep end, as so many others have.
There is a reason that both are now self publishing their punditry without editors or fact checkers. I wouldn't really even call it journalism anymore. Neither can still be compared to Ronan Farrow, who is meticulously honest.
