Which is better hair color wella or goldwell?

I personally think they are both very good for different reasons....depending on your clients desire for warmth in their finished color choice.... geographically you will find that some women like cooler results..(Wella) and some warmer (Goldwell)...I have worked with both for many years and for grey coverage..I have not found anything else to compare to Wella......for lovely shine and great condition after the color service..make sure you use performance plus....Goldwell is a lovely line for richness and reds.....I enjoy them both...
