Evian looks the nicest, and while it's not always a good barometer to go by, her reviews on the website are positive (fluffies and WKs perhaps?) Whereas the middle one only has 1 review to her name and the 3rd has a lot of not quite positives. Given that Diva actually publish critical reviews as well, it could show a mixed bag with number 3.
You're right to swerve all of KTs reviews though. Before he was exposed as the cunt he is, his reviews were a lesson in banal rubbish.
Hope whoever you choose gives great service. Sorry I can't help further.
