No doubt that Asus is better, in both quality and customer service.

Asus is the best PC brand, hands down. That's also a good laptop there.

Lenovo All THE WAY. It's the second highest rated brand behind Apple. They have plenty of models to chose from on their website. Anything from Gaming to Small Business, Lenovo has got it.

Can you guys say me which model of Asus is good?

I'd stick with Asus or Lenovo computers. I believe that Sony is ready to get out of the computer business and concentrate on it's mobile products. In reality it depends on what you will use your computer for. Lenovo is the old IBM brand. Very good computers. You'll see lots of "professionals" use Lenovo laptops, like insurance people, accountants, attorneys, etc. They all need reliable connections to their work.
