Samsung S90F 48-Inch OLED TV vs LG B3 Series OLED 4K TV

Both are 4K OLEDs with excellent contrast and near-instant response, so the choice comes down to size and motion. The LG B3 is the better pick for most people: it comes in 55, 65 and 77 inches, runs at a true 120 Hz, and supports Google Assistant, Alexa and Siri. The Samsung S90F is the one to get if you need a 48-inch OLED for a small room or a desk, and its anti-glare coating helps in bright rooms. Reviewers rate both highly; the B3 has far more owner ratings, and the S90F's smaller panel means fewer buyers.

• Choose the Samsung S90F if you have a tight space that fits a 48-inch screen, want an anti-glare coating, or prefer Samsung's Tizen smart platform with Alexa built in.
• Choose the LG B3 if you want a larger picture, a 120 Hz panel for smoother sport and gaming, or hands-free control through Google Assistant, Alexa or Siri.
