TCL C855 v LG C4 65"

Hi everyone I've been trying to work out what would be the best option for us TV wise but I feel like the reviews online don't really give me a clear answer, even though the refresh rate appears adequate for both. The TCL seems like great value for money however I'm always cautious about a significant price difference (I.e. there's a reason it's a lot cheaper). I'm certainly aware that OLED is more expensive to manufacture.

I have a room that's quite dark and we're planning to use as a mini-cinema type vibe. Main question is whether live sport would look really good with a TCL from a motion handling perspective, or if there's clearly some things that gripe from that perspective. Will use it for gaming, movies and regular TV too (in that order of use).

Any advice and recommendations re: above and any other pros/cons by users would be appreciated greatly! TIA
