Most trustworthy - these days, too hard to call! If pushed, the one I find least fake: Anne Dawson.
Most talented - multi-talented would have to be Jackie Kabler. She's the "writer" who actually managed to snag a proper publishing contract from the off, rather than starting out with vanity publishing.
Most knowledgeable - Charlie Brook. He's the one who still bothers to do proper preparation before a show, especially the jewellery shows. An honourable mention also to Miceal Murphy.
Most entertaining - accidentally, Chloe Everton, and Jill Franks!
Most sincere - Anne Dawson. Previously would have added Jackie Kabler to this one as well, but she's become quite false.
Best voice - Catherine Huntley has the most mellifluous voice.
Most classy - Alison Keenan.
Most witty - Charlie Brook.
Most funny - Alison Young.
Most natural - Anne Dawson.
Most bitchy - this is a four-horse race between Debbie Flint, Richard Jackson, Kathy Tayler and Julia Roberts - I detest the put-downs and digs at guests, fellow presenters, the gallery etc. I'm saddened that I've had to add any of them to this list as when I first started watching QVC I used to enjoy watching all four of these presenters. Sadly, they are a guarantee of a minimum of muting the TV now, for me.
