What brand's laptop will be the best for gaming? Asus or acer or hp or dell or lenovo?

Probably hp or dell in my experience but id look into alienware or origen if your a serious gamer

Alienware laptops are a bit overpriced for what they are but they do tend to have the best specs for gaming laptops.

Other than that I recommend looking at laptops from Asus and Gigabyte. Avoid Acer as those laptops tend to have high repair rates.

ASUS. Anyday!
