They are very similar turbos but i think the VF28 is a better all round turbo, the vf30 only flows a few more CFM but the VF28 is ball bearing. Both engines have the same power making potential. RA gears kick azz! Will the Ver 7 intercooler fit in a GC?
I have a Version 6 STI RA swap, and I love it, but if I was doing it from scratch, I would probably go with the version 7. What's not to like about the improvements? AVCS is great w/ better tq, it has the semi-closed deck where the Ver. 6 is an open deck design.

As for the VF-28, yeah, it's a great all around turbo and is probably ideal for a good all around street car / weekend auto-x car. Mine will be replaced soon and put into my brothers WRX.

I would go with the Ver.7... either that or get a wrx engine and a setup from Axis.

Oh, one more thing - if you are planning to do any ECU tuning, I would def. go with the Ver.7 You will have a much easier time finding tuners in the USA who can do ECUTek reflashes. The Version 6 ECU requires the Flash99 version of the ECUTek reflash software and as of right now, only a handful of people in the USA can tune them. Of couse, you could always go standalone or fit a piggyback of sorts, but finding support is much harder for the older ECUs (in the USA) than the newer ECUs, and standalone setups are $$$.

Hope this helps!
