This one is a trade-off between your priorities.
They're going to be similar in terms of viewing angles, but that's about it. For sports, the Samsung is going to look better, with less DSE, faster pixel response time, and a 120 Hz refresh with motion interpolation if you're into the SOE.
Movies are going to look better on the TCL, and HDR movies very much so. The TCL is massively brighter, has a much wider color gamut, and will have better black levels thanks to local dimming.
Those are my thoughts.
