I was a Goldwell rep for 3 years back in the 90's. I was really very convinced that Goldwell was tied for first place for lowest damaging with Scwartzkopf, a very similar color line from Germany as well.
Wella is not a bad line, but Goldwell does have it's advantages. Firstly, the pigments are smaller which means the cuticle does not have to be opened as much to get the pigment to deposit. Goldwell is gentler and has less ammonia, offering you less damage.
You're getting highlights so this does not really apply to you, but there is a semi-permanent, Colorance in the same color that is used to refresh the ends.. you never pull through the permanent color.. so you keep the hair in the best condition possible.
There is a drawback with Goldwell and that is, because it is more gentle, you need to do more to cover grey.. like using a higher ratio of color to processing lotion (called a bristle mix), or pre-softening with color and water to open the cuticle more.
I would say with one time highlights, you are not going to really go wrong with either color line, but if you're going to get them re-highlighted again and again, I would highly recommend using the Goldwell system. If your highlights fade you can always get a totally non damaging Colorance semi or use the Soft Color refresher at home.
I have not read much on the pintura method but assuming it is painting on the color freehand.
If you are planning on keeping your highlights, pintura may be great for being able to do the roots without double processing any hair.. matching up the root highlighting with the existing highlights would take a really experienced colorist to do well... I used to know a top stylist/colorist who could do foil method this way! It was amazing to watch him part the hair exactly and weave his comb in and out matching the hairs exactly.. the guy was a Michelangelo, I swear!
