What’s better S9 or Redmi Note 9?

[gam3r]

As per the title, uncle needs a new phone. Redmi note 9 is available for £120 new and the S9 is refurbished £164.

I’ve ordered the s9 but have I made a mistake ?

Assuming it's the normal Note 9 and the Exynos version of the S9, I would say the S9 is better in terms of raw performance and display, but the Redmi may offer better battery life and should still be supported software wise: https://www.gsmarena.com/compare.php3?idPhone1=10192&idPhone2=8966
