My Choice

Personally, I would choose the Nothing Phone (2a). While the Xiaomi 12X has better raw power, the (2a) offers a better balance of features for my daily use. The larger screen, longer battery life, more efficient chipset and more recent software combined with its unique design are more important to me. The slightly lower benchmark scores are something I can look past. I do like the inclusion of the 8K video recording in the Xiaomi 12X, but I don't need it and the Nothing Phone (2a)'s 4K is more than enough for my daily videography needs. Also the better selfie camera makes the Nothing Phone (2a) a better choice for me.
