TCL 5 Series/S555 2022 QLED vs TCL Q7/Q750G QLED

The TCL Q7/Q750G QLED is better than the TCL 5 Series/S555 2022 QLED. The Q7 has slightly better contrast and black uniformity, helped by a better local dimming feature. It also gets much brighter in both HDR and SDR than the S555, so the TV is better overall both in dark and bright rooms. Of course, the Q7 is a fully featured gaming TV, with support for up to 4k @ 144Hz on one HDMI port, so it's the better gaming TV overall, although the response time of the S555 is better for gamers, as it's more consistent overall. Ultimately the S555 doesn't have nearly as many quirks as the Q7, but it's also a less capable TV overall.
