Totally subjective. I know a few guys who think Kim Kardashian has a great ass. I think it needs to be painted gray, and have runway lines on it.
Peppers are the same way. I've have good and bad of every variety. I had a habanero once that tasted like dirty feet. I always cut them open just to make sure they aren't nasty inside. It looked just fine. Clean white seeds, no mold. Nothing wrong visually. It just tasted like gym socks. Out it went. I've also had them taste fruity and deliciously sweet. Not fictional sweet, but sweet as if someone put powdered sugar in them.
I've had tasty douglahs, and douglah powders. I've also had bitter nasty ones. I've had great yellow 7s, and some downright rancid ones.
I think it all depends on seed lineage, and soil/growth regimen.
