To each their own.
However I for one completely disagree with you. I have 3 completely normal females in my collection. However, one of those normals was selected for extreme lightness, and when bred to my vanilla male, produced offspring that were lighter and brighter than the vanilla pastels another breeder produced. He took his snakes to 5 shows before they sold, even though he had them very reasonably priced. Mine sold at the first show I took them to.
This season, my biggest normal female, who carries a lot of blushing, was bred to my fire male. And even though her babies have another month before they hatch, any fires that hatch are already sold. Just from the pictures of her and him, people are lined up to get her babies, because people recognize they should be excellent representations of the morph.
Two gene animals can be very nice that is true, but they can also be as poor or poorer than a single gene. I've seen Fireflies that were just as browned out as most Pastels, which results when people just throw any two animals together without considering the quality. I've seen Bumblebees I could barely tell apart from a Spider. I've also seen one Bumblebee who was so spectacular I would have sworn it was at least a three or four gene animal.
I've seen NERD stuff in person. Most people oooooh, and aaaaah over their 4 and 5 and 6 gene stuff. You wanna know something? I saw plenty of multi-multi gene stuff that was no more interesting than most normals. So what if it's a 6 gene first-of-it's-kind, if the snake is about as interesting to look at as drying paint. I saw a handful of single gene snakes at Tinely Park I had to back up and look at twice, and some of those multi gene snakes I barely glanced at.
