I guess it comes down to what we expect the groundstations to have for gain.

If we assume an AO-40 class station, it probably won't make a difference. If we're talking about some sort of handheld data device, that may be different. We don't need quite the same amount of gain that XM radio or Sat TV would require, from the groundstation perspective.
