Nothing 3a pro or Xiaomi 15T

Both phones, 3a pro 12/256 and 15T 12/512, are almost the same price, with $443 vs $457.

My major requirements are performance, battery, display and software with a decent camera. speces wise 15T looks good but i've nothing OS is quite good.

My main issue with nothing 3a pro is glass back panel. I am very clumsy and frequently drop my phone. I have shattered my display of current phone and replaced with cheap dispalys multiple times. 15T has plastic back panel which I don't mind as I will be using covers.
