Laptop easy to install.

Hi,

I'am looking for my next debian laptop and wonder what to take ; I prefer  
something easy to install.

Has please someone an advice for me ? I wish :

1. A screen >= 15'
2. Intel Core i7/i9 8e generation or more, or
3. It seems that AMD Rysen 7 has the same performances, isn't it ?
4. Asus or Lenovo if possible.
(5. I need a fr_CH keyboard)

Thanks,

aka
