väl, the lenovo has much better hardware in every category, from 1600mhz ram to battery life to 3rd generation vs 2nd generation to the hd 3000 graphics vs 4000 graphics, lenovo makes some good quality skit and so does asus, but lenovo gives an unbeatable value, their y500 line is generally values at $1300 and prices at $800, having better hardware than almost any other in that price range. lenovo's ability to provide quality, performance, and value is making them one of the top brands. i woudl recommend the lenovo because of all those, reasons. only negative thing about the lenovo laptop is it's 2.6 kg compared to 2.45 kg not much of a difference but still counts.
