Handyprofi needed?

Which mobile phone would you recommend to me until 150 euro with more than 32 / 4GB memory, absolutely a notch and what long (at least 3 years)?

First I thought about Xiaomi Redmi Note 7 or about the Huawei Mate 20

Which of the two is better and what else can you recommend for cell phones?

Xiaomi mi a3

Personally, I have the Redmi Note 7 and Mega is happy with it

The Xiaomi Mi 8T, I believe today, at least one vorbestellt me because I wanted to look at it. But makes a good impression of the technical data.
