I had a She-Ra and Bow when I was a kid, the other figures I only remember as impressions/images. Most of what I know is from the toy section of he-man.org.

Aesthetics- Peekablue 'cause I'm down with the peacock/stage magician assistant(imo) motif, Entrapta 'cause I like chrome, Angella's semi-translucent wings(here's hoping), Crystal Swiftwind/Moondancer/Sundancer 'cause they're see-thru
Concept- Double Trouble being a spy/counter-intelligence/espionage agent, Peekablue's clarivoyant powers
Avatar of the imagination- Netossa = gladiator, Jewelstar = female crystal/rock warrior(ala Stonedar and Rokkon)
Possible implementations/Curiosity/Anticipation- Glimmer's possible glow-in-the-dark accessories, Peekablue's feathers -will they be like Sy-Klone's ring and detach as a warfan weapon, will Mermista have a trident, how will her fishtail & legs be done, will the tail be bendy, can she stand with it on? How "Horde" will Double Trouble look(lady crossbow, logo/emblem?), Will Sweet-Bee's wings look like a bee's wings this time? Will Castaspella and Frosta have anything that spins?
Eye Candy/Side-kick/Counterpart factor- Sweet Bee's fights with Buzz-Off, Perfuma operates alongside Mossman (Wonder Woman/Wonder Girl, Superman/Supergirl, Batman/Nightwing/Batgirl(Babs), Hawkman/Hawkgirl)
Grandfathered in- Glimmer, Frosta, and Castaspella have a general likeability factor, I have no strong love for them, but will likely get them
On the chopping block Just saying...
Flutterina -yeah, because I want something as fast as a butterfly to be my scout/spy/messenger. unless she has some strong native american under/overtones I will probably pass
Starla - may fit in with NA as HQ eye candy, I have to see the figure
Tallstar - maybe counterpart to Extendar, I'll need to see both figures
Spinnerella - with kimono sleeves and blades, maybe. otherwise, i don't need/want a dancer
Kowl and Lookee - ...
Glory Bird - the birds I have are nothing more than accents as is, if I get one great, if not - no tears
So, those are some things that cause my individual like/dislike for characters from PoP.
