Sony A8F OLED vs Sony Z9F

The Sony A8F is better than the Sony Z9F, unless you consume a lot of static content and are concerned by the possibility of permanent burn-in inherent in OLED panels. The A8F has perfect dark-room performance, thanks to the perfect blacks provided by the OLED panel. The A8F also has better motion handling, with a near instantaneous response time, and much wider viewing angles. The Z9F does not have the risk of burn-in, and is much brighter, better suited for use in a bright room.
