Amazon Fire TV 4-Series vs Vizio Quantum QLED

Unless you're in a completely dark room, the Vizio Quantum QLED is slightly better than the Amazon Fire TV 4-Series. The Vizio has much better accuracy even before it's calibrated and has a much wider color gamut. The Vizio also has a very wide viewing angle, which is great if you have a wide seating arrangement, as the image doesn't look washed out at an angle.
