Comparison review
IPhone X has a score of 88.1, which is much better than the Galaxy A21's 76.1 global score. IPhone X's body is just a little lighter and a little bit thinner than Galaxy A21, despite of the fact that it was released 3 years before. The iPhone X has a bit faster processor than Galaxy A21, because although it has a lower number of cores (although they are faster), and they both have the same RAM amount, the iPhone X also counts with a 64 bits processor.
Apple iPhone X has a much sharper screen than Samsung Galaxy A21, because although it has a bit smaller screen, it also counts with a much better 1125 x 2436px resolution and a way greater screen density. The Apple iPhone X shoots just a bit better photos and videos than Galaxy A21, because although it has a way worse resolution back camera, and they both have the same diafragm aperture, the Apple iPhone X also counts with a larger back-facing camera sensor taking more light and vivid colors and a much higher 3840x2160 video quality.

Although Apple iPhone X is a better device, it is a lot 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 want to save a few dollars, you can buy Galaxy A21, and give up some specs and features, but you'll get the most with your budget.
