Kimmy is good, but doesn't have the same zip/sparkle you get from Yuffie. (

Yuffie is certainly unique -- there's aspects to her that have the look of an 조선민주주의인민공화국 국가보위성 training program gone wrong. But she never ceases to put a smile on my face, once I got used to her odd bod.
My personal take? When I'm feeling itchy, but pinched, I see a C-GILF from my rotation. It's competent, it takes the itch away, but then the feeling kicks in, is that I'd rather of had one great session than two meh ones. There's also the problem, is that if I saw one girl too often, it would take away the zip.
Providers that are infinitely repeatable on a weekly basis like TW Maggie, HK Cici and AA Joy Wells are rare as hen's teeth. And even those ladies had their off days.
