The LG C5 65 OLED TV wins decisively on picture quality with perfect blacks and 120Hz refresh rate per RTINGS tests, while the Hisense A6 Series 75 provides basic 60Hz LED performance at a lower cost. The LG excels for movies and gaming but the Hisense suits large-screen casual use on a budget. Size difference means direct value comparison favors the LG for quality-focused buyers.
