I'm using Redmi for years, no issues found for me. I have exchanged two redmi mobiles in 6 years, it was sold for a good price when I resell it.
I don't know about the other brands but I heard that Realme is a Redmi's competitor.
Redmi sucks,you will get ads while using device which could end up most annoying thing so better spend little more and get control of your mobile.
