Google Pixel 6a's construction is incredibly newer and a bit lighter than Samsung Galaxy A21's, although it's also a little thicker. Both phones in this comparison review use Android OS (operating system), but Google Pixel 6a has a newer 12 version and Samsung Galaxy A21 has Android 10 version, so it counts with a couple nice extra features.
The Google Pixel 6a has just a bit better display than Galaxy A21, because although it has a quite smaller screen, it also counts with a way higher resolution of 1080 x 2400 pixels and a lot better display pixel density. Galaxy A21 features a much powerful CPU than Google Pixel 6a, because although it has 3 GB less RAM, it also counts with more processing cores.
The Google Pixel 6a features a slightly better camera than Galaxy A21, because although it has a back-facing camera with a much worse resolution, it also counts with a lot better 3840x2160 (4K) video resolution and a larger aperture for better images and video in low light environments.

So if you want that extra specs and features, you can buy Google Pixel 6a, but if you don't you can save some dollars and buy the Galaxy A21, giving up some specifications.
