oneplus 5t

Hi everyone, Back few years ago, when the One Plus One just released, I was jealous of a friend who just got it day one. The design was a bit square-ish but it looked really cool and I remember it was really powerful for a smartphone of this price. And then, I never heard about One Plus...

Can you guys share me any reviews for smartphones Oneplus 5T and Samsung S8. In your point of view, which one is better and worth buying it? Thanks in advance.
