JochieSantiago Essentially Xiaomi and Poco are the same.. you'll get the same Hyper OS on both.
But, these are the things I would consider before choosing a Chinese brand.. The processor it comes with, how active the community is, and Whether I'll get a custom ROM if I didn't like the stock ROM..
Xiaomi's market share is crashing. Both poco and xiaomi didn't do well for the past 2 years. Hence they're selling their phones at more aggressive price.
So, Having a good processor (Snapdragon processor) would be my priority. Just incase if they're closing their operations and it's no longer getting official updates.. I can still flash custom ROM and extend it's life.
On spec wise your choice looks good. But, it comes with a mediatek processor which rarely supports custom ROMs. So, I wouldn't choose this. But, it's your choice. Have fun with your new phone.
