Favorite ring bearer

I'd have to go with Bilbo. Not because he was good at the 'job' of Ringbearer, but because of the romance that (for him) went along with the Ring: he would always associate the Ring with the great adventure of his life, the Mountains and the great Forest and the Dragon. It is unfortunate that the world became more hollow for him after he gave up the Ring, but with it he was a confident trickster, a joy to his nephews, and a bit of a mystery even to Gandalf.
