This is impossible to answer with just one, because it changes constantly! Also, it depends on finding a really gorgeous example, or with the hets, on finding a good price from a breeder I can trust. However, I can say that if I found equally beautiful options for all of these at the same time, but could only afford one, I'd probably get the male lesser.

male lesser
spider (not sure which sex, might just get whichever sex I find a stunning one)
pinstripe (not sure which sex, as above)

het or phet clown females
het or phet g-stripe females
het VPI axanthic, phet albino female
