If you can get past the unconventional names they use for the colors, the Citadel paints aren't bad for larger scale figs. A little difficult to handle as the drying agent in them gives you no time to work the paint. A problem on the larger surface areas and coverage needed for larger figs. I've found that if you thin them, they work o.k.
I primarily use Tamiya and Model Master acrylics and then Oil paints for blending and highlights. On the occasion that I've used the citadel paint is when I've been unable to replace a color or there is a particular color that catches my eye. There is a gaming shop close by and I'll patronize them if I'm not headed to my LHS.
Wayne, I don't blame you. Metallics are difficult to begin with, and the Citadel metallics are worse than most. About the only metallic I'll use of theirs is the gun metal. I like the bluish color for some applications.
I have heard several good things about the vallejo colors and you might want to give them a try.
Since larger figures are more for display rather than gaming figures which are handled more frequently, a good rule of thumb for painting figures is "whatever works." I've used all types of paint with great success and the more you are open to trying new stuff the more you'll find. I would also suggest even some of those Americana or Ceramacoat acrylics you see in craft stores. They come in as many if not more colors than conventional model paint and once the figure is primed, the adhesion is not a problem. They are inexpensive, go a long way, last a long time, are easy to mix, you can run them through an airbrush. They blend well, and are some of the best paint I have found for drybrushing. Best of all, there are more craft stores than hobby shops and that means you can find them everywhere.
