It’s time to buy an iPhone SE3?

I’ve had my iPhone SE 2 128gb since late 2020. And it’s kinda struggling. I got a 3rd party battery change which is been fine (no sudden drops/false battery) and kept it going for another year. But I’ve dropped this one enough (or just old) so that half the time the screen has burn-in and black lines across it.

I’ve found a new (not refurbished) SE3 256gb for about £280. My SIM contract has 5G included. Seems like a no brainier, but wanted to get some ideas on the price? Can’t find many refurbished 256gb models that are cheaper (without damage/used battery) so this seems like a good deal
