Futzing with Metallics

After reading this post I decided to get some Citadel metallics, and... I'm debating whether I agree. The post claims that Citadel's metallics are higher quality than Vallejo's, but I'm having a hard time seeing any advantage at all to the Citadel metallics--they are uniformly less pigmented yet thicker. I'm not really seeing much difference by way of the claimed difference in mica flake size; after five coats of lightly thinned Citadel Burnished Gold, I'm almost but not quite to the coverage of three coats of lightly thinned VGC Polished Gold. However, the texture is much smoother, and I'm not seeing much by way of flattening the surface out, so maybe it will ultimately look better.
