Which laptop is better? Lenovo y510 or asus n550?

It depends for what you're gonna use it,
If it's for gaming or things like that lenovo, if it's for normal things asus

but if i have to choose one, it would be Asus

Asus sucks I have one rn & the keyboard always messes up and the mouse always randomly clicks off stuff & whenever you need help online it's hard to find bc it's a Japanese brand & everything's in Japanese
I'd go with the lenovo
