In general, The Lenovo S410p is better. Both have same processor i5 4200U. But the lenovo has following advantages:
* Better Graphics Performance (due to dedicated graphics card GT720M which is much better than HD4600 in ASUS)
* 1 TB HDD vs 500 GB in ASUS
* Windows 8, whereas in ASUS you're getting DOS (You''l have to buy Win8)
