TonePort - Upgrades?

[Gasp100]

I have the UX1 Toneport and some of the models/sounds are pretty decent a/b'ing against Guitar Rig. I'm wondering if one of the more expensive model pack upgrades (either the Triple Pack or Power Pack) for $99 would give me BETTER models vs. more stuff? I think the Power Pack gives you basically everything in a Pod XT so I'm wondering if the models are better or if there is just more. Any POD people please chime in...
