I voted for a few of the named (Laura Geller #1 naturally), and Leighton Denny while we still can... but I've put Other to cover:
Kathy Kangas
Charlotte Knight (Ciate) - she reminds me of Paloma Faith
Alyson Hogg (Vita Liberata) - new arrival but has quickly become a favourite for me
Joanie for me as she's the only one that doesn't spout what sounds like absolute made-up tosh about what it can supposedly do for you! It's more a case of "this lipstick will look classy and glamorous" rather than "this lipstick will erase all the lines on your face and make you look 20 years younger"!
