Moto G84 vs OPPO A78 5G
The Verdict
Moto G84 delivers noticeably better value at $279 despite costing $30 more than OPPO A78 5G. The display quality gap is substantial: Moto's 6.55-inch P-OLED panel reaches 1300 nits brightness with 120Hz refresh, while OPPO's 6.56-inch IPS LCD maxes out at 680 nits and 90Hz. Performance-wise, Snapdragon 695 edges out MediaTek Dimensity 700, and Moto includes 6GB RAM standard versus OPPO's 4GB base model. Camera experience favors Moto significantly with optical image stabilization on the 50MP main sensor, plus an 8MP ultrawide lens OPPO lacks entirely. OPPO does offer better dust and water resistance with IPX4 rating compared to Moto's IP52, and weighs 20g less at 188g. Video recording capability differs markedly: Moto shoots 1080p at 60fps while OPPO maxes at 30fps. Both pack identical 5000mAh batteries with matching 33W charging speeds. For most users seeking better daily display quality, camera versatility, and raw performance, Moto G84 justifies the slight premium.
