The LG G5 OLED 83 outperforms the Sony A9G 65 on every modern metric including 1500-nit brightness versus 750 nits (RTINGS) and current webOS features. The 18-inch size advantage further widens the gap for most viewers despite higher cost. Sony A9G remains a capable older OLED but lacks the updates found in 2025 models per CNET comparisons.
