I really can't answer that. I could list each character and tell you why I like him or her.
Do so! It will be interesting to read. I'll post my list:
Sam: I love his devotion to Frodo, and his humour. I feel like I am Sam by the end of the book, even though we are not very a like.
Frodo: I can relate to him the best of all the characters, I love his way of thinking, and of course the way he takes the Ring all the way to Mordor.
Strider: I like his mysteriousness, but only when he is Strider.
Gimli: He is funny.
Legolas: I like his love of nature, and the many insightful things he says about the world from the Elves point of view.
Gandalf: How could anyone not like Gandalf?...
Faramir: He is very wise and just as much of a 'kingly perrson' as Aragorn.
Galadriel: I like her sadness. (I know it sounds strange)
Elrond: I like the way he just sort of sits back and moves things with his wisdom.
Glorfindel: I like his mysteriousness, and of course Tolkien's description of him is one of the best in the book: 'his face was fair and young and fearless and full of joy, on his brow sat wisdom and in his hand was strength.'
Cirdan: Another mysterious elf, I love the way that he loves the Sea.
Tom Bombadil and Goldberry: They are stranger and freerer than anyone else in the book.
Pippin and Merry: They are funny, and I like their optomisim.
Now that I've named like all the characters I'll stop... ;)
