I was faced with the same quandary when deciding to "trade-up" from TMA equipment : the assumption I made was that the 861v6 is simply state-of-the-art in all respects compared to it's brethren & the competition. Even the smaller form of the G-series forces compromises that ought not to be a constraint in the 861 series, topology & technology are other factors.
If my assumption was wrong, then I'll be one very unhappy bunny !
