WD My Passport vs My Passport Essential?

What is the difference between this two:

My Passport Essential

There is no difference in price at my supplier, so I just want to know which one to pickup?

And also another question. Recently I bought a Buffalo MiniStation Extreme 1TB. Really nice portable drive and quite fast also! But the drive within is 5400 RPM, so I've been thinking: Can I get higher speeds if I pickup a drive with USB3 and 7200 RPM? If yes:

Has somebody tried the Samsung S2 Portable Drive USB 3.0 (7200 RPM)? Is it a better drive and should I get that one instead?

So, what is the difference? Tell me! I can't see.

The My Passport Essential are the previous gen. The My Passport are the newer drives.
I've had both and other then the physical differences, there's nothing much else in it.
