Our Verdict

Hisense U6N

TCL S551G

The Hisense U6N and the TCL S551G are both entry-level TVs, but the Hisense is better overall thanks to its local dimming feature and significantly better contrast. That, combined with its higher peak brightness, provides much better picture quality and a more impactful HDR experience. That said, it has a worse viewing angle, so it's even less suitable for wide seating arrangements.
