i5 or i7 ??

Hi, im trying to select a new computer processor, but, i dont know which one is the best between this two processors:

Intel® Core™ i7-4500U  and  Intel® Core™ i5-4440S  i though that always core i7 is better than i5, thats true?? Somebody can guide me?

Here is the comparison table (http://ark.intel.com/compare/75040,75460)

Thank you.
