Realizing that an animal can be quite an individual & defy the rules that generally categorize it's species:
Mex Black
Most docile, great feeders. Top choice.
Cal King
Juveniles tend to musk, but adults are very aggressive eaters and handle well. Desert phase specimens are especially confident & curious.
Desert
Great, all-around specimen. Great feeders.
Easter
My first King, named Solomon. He handled great, and loved to customize his home.
My pick? I have a Cal King, Mojave Desert phase. Although he has beautiful, crisp colors & patterns, I've learned to choose based on:
1) Personality, enjoys being handled & interacting with Human.
2) Aggressive feeder
3) Curious, confident, spirited.
