I've just started using M.A.C's Lip Conditioner this past week after we got the Viva Glam edition sent to my offices. I really like it so far, it's got a great consistency, seems to last for a while after applying, and smells, of all things, like cream soda.
Another one that I had been using and liked was MALIN+GOETZ's lip moisturizer. It's got a different consistency to it that most tube balms I've come across (not as greasy) and if you put too much on it can easily look like lip gloss and get that tacky feel to it, but it works well.
