I think i dislike Blood Parrots more out of sympathy than actual hate. Some look nice, but the deformity is sad looking. Especially the cheap ones i've been seeing in PS lately that almost have a functioning mouth, but not quit.
Africans also aren't among my favorites because for the most part they lack the personality of CA/SA (but there are exceptions to this).
Most central Americans. especially flowerhorns... its awful i know. i LIKE most africans, dwarf cichilds, cichla, and south americans like severums and discus and Uaru
