When both these tools are set to a baud rate of 115200 (typical), the speed difference is negligible. However it is much easier to set the baud rate in the SX, and so we recommend this unit if your are going to require faster rates (up to 2Mbaud).
The SX receives its power from the USB rather than from your vehicle. This allows you to communicate with your tool without being plugged into the vehicle if this is something you wish to do. Of course you would not get vehicle information without being in the vehicle. The ELMScan 5 gets its power from the OBD plug and so you must be in a vehicle in order to use this tool.
Hope this answers your questions,
