David,

For data mode operation, most applications use only the left channel, 
but there are a few that can swap channels.  I would stick with a stereo 
device for the most flexibility.
And, if you want to use the soundcard for some other purpose (such as 
for SDR purposes - like the KX3 I/Q RX output), you will need both channels.

In other words, more flexibility, wider bandwidth and better audio noise 
characteristics than the SLUSB provides.  The bandwidth is not important 
for data mode operation, but is a real asset for SDR use.
