It isn't that I think Spiders are ugly, per se. They just don't interest me. And so many people have them.
Bumblebees were one of the first morphs that got me interested in BPs. But ultimately I like morphs that really clean up nice and are higher contrast, such as Deserts, quality Mojaves, Lemon Pastels, Genetic stripes, etc.
Like you said, it is all opinions. I would never try to talk someone out of a Spider if that is what they wanted for their collection. It just probably won't be a flavor of mine.
