While quality is subjective, there most efinitly are low and high quality examples of every morph.
High quality examples leave ZERO doubt as to what the mutation is. Look at a screamer Yellowbelly compared to a "subtle" one. In theis case quality = strength of the morph phenotype. IMO this is not terribly negotiable.
Now, quality in realtion to other factors, such as "clean", "busy" etc... leaves a lot more room for interpretation.
As for the OP's original question. IMO the answer really is no. There are high and low quality examples of everything that I can think of off the top of my head.
Well said! I was referring more to busy and reduced pattern animals. Different people like different things
