Sampler?? You have got Variphrase!!!! That means you can play voices over the keyboard, playing chords etc. This is the specialty about the VA-7. That has never been shown before.

And yes, the Roland VA-7 is more suitable for home use. There is a simple reason for that: Roland has the G-1000 for Stage use. Otherwise they would be concurring themselves. SO buy the G-1000 for Live Performance and use the VA-7 for home (cause it has speakers).
