Just a matter of design choice in the type of plug connections used.

Both units are only a single stereo channel inputm regardless of the number of apparent physical connections.

That means that you can only record to two mono tracks at a time, at most. For example, a mic into one channel and a guitar into the other.

The use of the single combination XLR/quarter inch jack is just a better space saving situation. It is still an either/or situation with either unit. Nothing to be gained by having the plugs separated.

If you want or need to record to more than one stereo channel (or divide that into two mono channels) then you have to forego USB connection, as it doesn't have the needed bandwidth and look into a multiple-input soundcard situation. More money. More complication. If you don't have a computer with a PCI slot available, such as a laptop or one of the smaller desktops, then FireWire connect is the choice for multiple channel input at this time. That also has its complications. For instance, if your computer has a FireWire port on it, you should first make sure that it is using the TI FireWire interface or the soundcard may not work.
