The LG C5 OLED 65 Inch outperforms the Hisense A6 Series 4K 65 across picture quality metrics with infinite contrast and 120Hz refresh rate as measured by RTINGS and Tom's Hardware. Hisense provides solid value for casual 4K viewing at a lower price but lacks the depth and gaming capabilities of the LG. LG C5 is the clear winner for most users seeking current-generation performance.
