Our Verdict
TCL Q651G
TCL Q5/Q550F QLED
The TCL Q651G and the TCL Q550F are very similar, and you should get the cheapest one you can find, or get the model with your preferred smart operating system, as the Q651G uses Google TV while the Q550F uses Amazon's Fire TV OS. When it comes to performance, the Q550F has the better contrast of the two and is also a bit brighter with better reflection handling. The Q651G is the more accurate of the two TVs, with generally better image processing.
