smartphone for gaming

Hi

My OnePlus 6 is dying so I need a new one and I want my new phone to run games like Wild Rift or Genshin Impact smoothly. But, while searching for gaming smartphones on YouTube and google I noticed that most gaming phones have “gamer” aesthetics and I don’t like it, I prefer sober designs.

The Black Shark 4Pro, seemed a bit more sober than the other phones and affordable, how does it looks in person? Please give me any recommendations for a new smartphone.

My maximum budget is around 800 euros.
