going to entirely depend on what panel there looking at, setting, panel etc. being better for TV and movies does not necessarily mean vibrant alone, Motion handling for example plays a role as does the special sauce each manufacture applies. Having seen a friends A8H (socially distanced) would have been my pick over LG models if only Sony had comparable gaming features. Panasonic, more so there custom Pro models seem to be in a different league entirely. But they are expensive as the OLED panels are actually cherry picked by LG display. There HZ2000 seems absolutely spectacular, abit expensive as!
That said, not going to go wrong IMO with LG TV's at all, they are damm fantastic, just some of the others are slightly ahead / behind in there own areas IMO. Panasonic HZ1000 could be a nice option to look at, great panel overall comes with DV and HDR10+, natural colours, good near black handling and not massively overpriced but does lack HDMI 2.1 and the gaming features.
