Well the question was "Warmest/sweetest GFE provider", and the poster said he prefers curvy, +30 women, so I don't know what "youthful and Pageant material" has to do with it. She might be around 30 though, sure; most SPs shave a few years off in their ads. But I will say that some of her photos really don't do her justice. I think she's quite lovely, and certainly not "worn" by any means.
As for the cost, I think she's worth the money, but I book more than an hour with her anyway, so it works out to slightly less per hour than $320.00. Guess it depends what you're looking for, though. I find her very attractive, she's great at sex (BJs especially), and she makes me feel comfortable. And I feel like we're actually being intimate, not just fucking. Works for me!
Also, I guess it depend on what "girlfriend experience" means to you. A lot of the time GFE seems to mean that the SP will give BBBJs, allows DATY, deep kissing, etc. But for me it also means someone I can talk to, someone I find interesting, intelligent, funny, etc. Like someone I might actually want as my girlfriend! Clementine meets those requirements for me; maybe you have different preferences though.
