Comparison review
Asus ROG Phone is a bit better than the Galaxy A21, getting a 77.1 score against 76.1. Despite being the best cellphone we compare here, we must highlight that it is also an older, a little bit heavier and just a bit thicker cellphone. Asus ROG Phone has a bit more powerful processor than Galaxy A21, and although they both have 8 processing cores, the Asus ROG Phone also has 5 GB more RAM memory.
Asus ROG Phone has a brighter display than Galaxy A21, because although it has a little bit smaller screen, it also counts with a higher pixels density and a much better 1080 x 2160 resolution. The Asus ROG Phone features a much greater memory capacity for applications and games than Galaxy A21, because although it has no slot for an SD memory card, it also counts with 512 GB internal storage.
Asus ROG Phone's battery lifetime is very similar to the Galaxy A21 one. Samsung Galaxy A21 takes much clearer pictures and videos than Asus ROG Phone, although it has worse 30 fps video frame rates and a smaller sensor which offers a worse photo and video quality, they both have the same video definition and a same size diafragm aperture.
Although Asus ROG Phone is a better device, it is way more expensive than the Galaxy A21, and it doesn't have such a good relation between it's price and quality as Galaxy A21. If you prefer to save some money, you can get the Galaxy A21, giving up a couple features, but you'll get the most with your budget.
