A Zoa is a Zoa. Colors vary, but I don't think of any of them as "high end".
Take "high end" Zoas and put them next to "regular" Zoas in the same tank and they will perform equally based on the conditions.
Marketing makes them "high end".
Hahaha! If only that were true!
I consider any zoa that costs more than ~$80 per polyp to be "high end"... And I'm not talking WWC pricing. Everything from them is that expensive!
Some is marketing, some is difficulty and some is availability. The list posted earlier is a good start.
