A USB 3.0 is the future aware choice in today's market.
Over the last two years there has been a steady release of faster and cheaper USB 3.0 drives but most retailers are still pushing their old stock of slower USB 2.0 models and unaware consumers are missing out on faster USB 3.0 speed. USB 3.0 is fully backwards compatible with USB 2.0 so even if your computer only has a USB 2.0 connection USB 3.0 drives perform better making them the clear, and future aware, choice in today's market. The typical USB 3.0 speed for flash drives is 30/90 MBps read/write vs. 10/20 MBps for USB 2.0. Using a USB 3.0 drive on a USB 2.0 port nearly always results in speeds capped by USB 2.0's limits, so using a fast USB 3.0 flash drive on a USB 2.0 port will normally result in read/write speeds of approximately 30/30 MBps read/write, more than double the typical speeds reached by a USB 2.0 drive.
