There are some nice features of the FSG2T over the FSG71M. The dedicated single knob squelch control that Kevin 2B mentions comes to mind.

One feature of the FSG71M that I wish was in other transceivers - the dedicated single knob frequency memory selector. During soaring travels I set up memories for the host airport unicom, AWOS, 123.3 and 123.5, then maybe other area airport's unicoms. Makes is very fast to move between frequencies.
