Probook vs Inspiron

[Ravian]

Hello guys...
What should I get from Hp Probook 4540s and Dell Inspiron N5520 if both have exactly same specs?
What I am considering is, Intel i5 3210M and 1GB AMD HD7670M. Both models have same.

whichever is cheaper or is more appealing to the eyes.

Also, what about the battery timings of both?
