In my opinion, all are beautiful in their own right. Personally, I tend to lean towards Picasso's or Ocelaris'. Both breed well and are pretty tolerant in home tank conditions. I don't ever knowingly purchase anything wild-caught, as this is, in my opinion, not only destructive and unecessary, but can also introduce disease and parasites into your home invironment.
Tank bred species may seem "faded" in color, but most of that coloration has to do with proper diet and water conditions. Wild fish are in the best tank of all - the oceans, and have at their disposal, an array of live food choices, so their intake of natural vitamins and essential fats, as well as minerals, is far superior to most home-tank residents. Additionally, the wild gene pools are much more vast, so there is rarely incestual couplings of which can alter coloration, physical appearance, health and demeanor of the animal.
Feeding live foods, a wide variety, and supplementing the waters with natural elements is the best way to not only raise healthy fish and tanks, but also to get that rich coloration many hobiest adore so much in wild animals. We don't need to pull them from the ocean's, we simply need to provide them with what the ocean's do, and try our best to ensure we purchase tank bred species from reputable suppliers (who do their best to vary their own captive gene pools with mixed spawn, to avoid incestual outcomes).
