Which Gold and Silver Airbrush coloring cover best

I need a little help with selecting gold and silver for my airbrushing, purchased a small gold and silver by Duff from Michales, i didnt like the covering, to me the effect was more like a luster instead of an actual gold.  So iam in the process on purchasing these colors.  Iam tore between, Americolor gold/silver and Lucks gold/silver shimmer.  Has anyone every used either or both of these two labels.  Any feedback is helpful.
