Asus laptop generally have decent value for their price. The E-PC lineup leaves a bit to be desired for its pricepoint but the RoG lineup certainly isn't bad at all.
HP is abysmal all around, avoid like the plague.
Sony laptops aren't half bad construction wise but leave a lot to be desired in the internals. They're also a little bit pricey, I'd personally say that Asus laptops have better value
I have no experience with Samsung laptops
