In addition to MT's advice: How old is your computer? Is it due for replacement soon? If so, it will likely come with a USB 3 port - my recently new laptop has one USB 2 and 2 USB 3 ports.
If you think you'll be replacing the computer soon, or if it is a new computer with a USB 3 port already installed, go for the card reader with USB 3 connectivity. You won't believe the speed... ;-)

Right! USB 3.0 is definitely faster. Get a new computer. :D
