Nice comparison. The styles do sound very similar although being used to the T2 I found the guitar parts and drums of the T2 style slightly more upfront than the G70's.
Nothing wrong with either of them though, the G70 style was nice and the accordion was great to hear.
* Not all of the waltz 3/4 styles sound like a German oomph pa pa, there's plenty of variation internally and on the net.
