Growing up in the northwest this was 100% my opinion going through Yellowstone. The thing that makes Yellowstone cool is the animals, there are much better viewing experiences in other parks. But seeing herds of bison, or bears and wolves is incredible at Yellowstone. Grand Teton on the other hand felt undersold with its beautiful vistas and lack of traffic.
