They all go in the same quarter mile of canyon, simultaneously. So the only differences are the seating space on the five minute ride, and what you pay.
It is typically badly crowded, sometimes you can’t see the floor- like at a concert. The only way to avoid it is to book one of the special ‘photographers’ tours over noon. You need to have a camera with exchangeable lenses (or they say you are not a photographer), and it’s going to cost you around 100$, or more.
Very ugly, but that’s how it is. There is only so much canyon, and so many people that want to see it.
