The Google Nexus 6 has a global score of 81.1, which is just a bit better than Galaxy A21's score of 76.1. Despite of the fact Google Nexus 6 is extremely older and thicker than Galaxy A21, it's body is still a bit lighter. Both of these phones include Android OS (Operating System), but the Google Nexus 6 has the older 5.1 version while Galaxy A21 has Android 10.
The Google Nexus 6 counts with just a little better performance than Galaxy A21, because although it has 4 lesser processing cores (although faster), and they both have the same RAM memory amount, the Google Nexus 6 also counts with an additional graphics co-processor. The Google Nexus 6 has a much better screen than Galaxy A21, because although it has a little bit smaller screen, it also counts with a much better resolution of 2560 x 1440 pixels and a way better count of pixels per screen inch.
The Google Nexus 6 has a bit better camera than Samsung Galaxy A21, because although it has a less mega-pixels camera and a tinier aperture which is not so good for shooting photos and videos in poorly lited environments, it also counts with a way higher 3840x2160 video definition. The Galaxy A21 features a much greater memory capacity for applications, games, photos and videos than Google Nexus 6, because although it has only 32 GB internal storage capacity, it also counts with an external memory card slot that admits a maximum of 512 GB.
The Samsung Galaxy A21 has improved battery performance than Google Nexus 6, because it has a 24 percent bigger battery capacity.
Although Google Nexus 6 is a better device, it costs a lot more money than Galaxy A21, and it doesn't have such a good relation between it's price and quality as the Galaxy A21. So if you need that extra specs, you can buy the Google Nexus 6, else you can save a couple dollars and buy the Galaxy A21, resigning some features and specs.
