We didn't switch from anything but have used GS NC since formula was introduced at 8 mos. I had a free sample and she took to it, so I never switched. Keep in mind, it's the most expensive, sometimes tough to find, and never on sale.
that's good that it's cheaper. I just found that BRU would only carry a small stock of it (that's the cheapest place I've found it). And when they do coupons it never includes GS NC.
that's the only kind my sil gave her sons. i gave ryan gs toddler formula just until recently. he seemed to like it and had no problems with it. i just couldn't stand the smell so i just switched to whole milk.
