I am a
freak about the full-size MAC brushes, I

them to death!! I only have a few travel ones (I got the Buff and Line set this year) and they are good -- better than most travel brushes, IMO -- but on the whole not
quite as awesome as the full-sized ones, with a few exceptions. For example, I have some travel-sized MAC brushes from a few years back that I use just as much as my regular MAC brushes -- and the very small 209 (eyeliner) brushes that I got in my Chocolate and Naughty Noir eye kits this year have turned out to be wonderful.
