Yes, more of a matter of the hardware design though and operating systems, not really specifically software. I mean, software gets loaded into hardware after all, and you go from there.
So true, if there is a processor there is software.
I don't know about the pedal so I just talk about the application itself.
GR is really a great application which competes very close with the POD for sound, but as said before you have to run it through the computer.
If you consider software take a look at AmpliTube too. I think there is a demo of their software available.
My opinion is that I liked the sound in AmpliTube better but the userbase and community was bigger and there was more homemade soundpathces available for GR.
Sum of it: Soundwise I liked AmpliTube better, I liked the GuitarRig application and community better than AmpliTubes, and finally; I bought a POD XT.
I have a POD. My son have GR. My son like GuitarRig better than the POD. Go figure

Matter of taste and how you use your gear.
Oh, forgot some information that might be useful.
In GuitarRig you can record either a clean signal or with effects (dry and wet?) and with a clean recording you can add whichever effect you like on that. If I remember it right then you can use GuitarRig as a VST.
I think the same goes for AmpliTube but I never got that far with it.
