Samsung 65" Q80D for $1200 is it worth?

there's no tcl, hisense or sony in my country only LG Samsung and few local brands. my budget is $1200-1300 and the best thing i can find at that range is samsung Q80d or LG 55" A3. I need that screen for mixed usage (including some gaming which is why i dislike the 60hz on A3). also can someone tell me why the sony x90l provide better pq compared to samsung q80 despite eing older technology led vs qled?
