These are both very good but also different. I think I agree with the general consensus to this point that the T2 version sounds a little more polished and that the G70 sounds a little looser and more like a band.
For me though, polished isn't necessarily better.

Specifically, I like the bass and drums a bit better on the G70, and the lead instruments a little better on the T2. No surprise at all for me, as I've pretty much always felt this way about Yamaha arrangers and Keys.

This doesn't make my choice any easier guys. I think in the end both boards are gonna sound very good to me when I A/B them next week, and if so, for me it will likely come down to ergonomics / user interface, Vocal harmonizers, SMF playback, and physical feel of the keys.
