Samsung 4K Mini LED Smart TV vs Roku Plus Series 55" QLED Mini-LED TV

Both are 55-inch 4K Mini-LED sets, so the real split is the software and the picture processing. The Roku Plus Series adds a QLED layer, Dolby Vision, HDR10+ and Dolby Atmos, and its Roku OS is the simplest smart TV interface to learn. Samsung's set brings the stronger panel tuning and upscaling that owners of its Mini-LED models praise, plus Google Assistant and Alexa built in. Pick Roku for the best picture spec sheet and the easiest interface; pick Samsung if you want the more polished image processing and a brand with deeper service coverage.

• Choose the Samsung if you want the more refined picture processing and both Google Assistant and Alexa on the TV.
• Choose the Roku if you want QLED color, Dolby Vision and Dolby Atmos with the simplest smart TV interface.
