750/255 or 750/650 - How much do you use your 650?

[DesertNomad]

I have pulled out my GNS530W and KX155. In their place I have bought a GTN750 and am now deciding on the second radio. I had planned on a GNC255 Nav/Com, but a few local pilots are suggesting a GTN650.

For those of you that have a 750/650 combo, how much do you use the 650 for something other than a simple Nav/Com radio?

I can see displaying fuel flow on it is useful as is the Default Nav screen.

Thoughts? It is a $6K difference in price.
