I use both. I have:
Convert gloves that kinda suck cause the non removing liner gets pulled out from the fingers and is a pain in the a$$ to get back in. Also not as waterproof as they claim. Booo!
180's thin tech gloves that are like liners but warm, with little nibs on the palm to grip and operate Ipods and cellphones. I love these.
DaKine mittens that I got as a xmas gift, which was strange cause it's what I would have wanted but got from someone that I had no idea was getting me something. Still haven't had a chance to wear them for boarding but warm and great for making snowballs.
Forum Love Gloves that I used a couple of weeks ago for the first time. Got soaking wet and still kept my hands warmer than not wearing anything at all. Think weatherproofing might help with the wetness. But made out of leather and definately a spring glove. Pretty sweet looking in white and gray.
