My Choice

I would choose the Asus ROG Phone 8 Pro. The difference in performance is astronomical, with the ROG Phone 8 Pro having an Antutu score more than 10 times higher than the Moto G Power. The screen of the Asus is AMOLED, 165Hz, with 2500 nits of brightness; This is a big difference, especially for content consumption and gaming. The camera is also dramatically better and provides more options, thanks to the extra lenses it has. Lastly, the Asus has much better future proofing due to having a modern chip, newer version of Android, and significantly more RAM and storage. The only thing the Moto G Power has better is the battery capacity (5000mah vs 5500mah), and its weight, but those benefits don't justify choosing it over the ROG Phone 8 Pro. The Asus ROG Phone 8 Pro is the obvious choice if you value overall performance, display quality, and camera capabilities.
