Galaxy A21 counts with just a bit better performance than HTC U Ultra, because although it has 1 GB lesser RAM, it also counts with a greater number of cores (and they are faster).
The HTC U Ultra has a slightly better camera than Samsung Galaxy A21, because although it has a back facing camera with lot less mega-pixels, and they both have a F1.8 diafragm aperture, the HTC U Ultra also counts with a way bigger camera sensor capturing more light and vivid colors and a lot higher 3840x2160 (4K) video quality.
The Samsung Galaxy A21 has superior battery performance than HTC U Ultra, because it has a 4000mAh battery size.
Although HTC U Ultra is a better device, it costs a lot more than the Galaxy A21, and it doesn't have such a good price and quality relation as the Galaxy A21.
