Samsung M70HD Mini LED 4K TV vs Acer M Series 75" 4K Mini LED Google TV

The Samsung M70HD is the safer pick for most people: it comes in 50, 65 and 85 inches, has three HDMI ports, and carries a strong 4.8 rating from 1,500 owners. The Acer is the better fit for a large, bright room where gaming and sports matter, since its 75-inch panel runs at 144 Hz with a 178-degree viewing angle and a 60 W Dolby Atmos speaker system. Samsung's Tizen is polished and familiar; Acer's Google TV bundles more apps out of the box and adds an energy saving mode. Build quality is close on both, and neither is a premium flagship.

• Choose the Samsung M70HD if you want a 50, 65 or 85 inch size, three HDMI inputs, and the simpler Tizen interface backed by a large base of owner ratings.
• Choose the Acer Mini LED if you want one big 75 inch screen, smooth 144 Hz motion for games and sports, and stronger built-in sound with Dolby Atmos.
