Erik,
Hard to say since I have never seen any direct comparison of real results between the two. However, based on various factors I decided that for purposes any possible improvement in possible image quality did not warrant the considerable extra cost of the V750. If you need the extra bundled software that comes with the V750, or the fluid mount station, others might decide differently.
I have been pleasantly surprised by the quality of the V700, once the holders are adjusted for the optimum plane of focus. The scan quality is definitely good enough for prints up to 16X20 size from 4X5" negatives IMHO.
