With mechanical HDD's seek time, spin speed and interface are three of the main indicators of speed. Both have identical seek times and spin speeds. However, the WD is SATA III and the F3 SATA II. SATA III is the latest interface which allows higher data transfer speeds so in theory the WD should be faster.
From what I have read the WD Blue isn't really any faster than the F3 though so you may as well get the largest capacity as there's probably little noticeable speed difference between the two drives.
