Our Verdict
LG SM9000
LG B9 OLED
The LG B9 OLED is a much better TV than the LG SM9000. Thanks to its OLED panel, the B9 has perfect blacks and excellent viewing angles. It also has much better gray uniformity than the SM9000 and does a better job handling reflections. The B9 is also a better choice if you watch a lot of sports or play a lot of games as it has much better motion handling. On the other hand, the SM9000 has more accurate colors out-of-the-box. The SM9000 also doesn't run the risk of permanent image retention or burn-in, like the OLED panel on the B9 does. This likely won't be an issue for most OLED owners who watch normal, varied content, but can be a concern if you watch a ton of static images.
