I've never liked Sam. He's too . . . earnest or something.

By miles

Frodo is a far deeper character, I find him more interesting.

Sam is very kind.

Frodo is a useless whiner, who never does anything and always has to be saved. Heck, he didn't even do his job in the end. I'm neutral about Sam, but he's better then him.

Sam is a mean servant, who just sticks around and acts like he has charisma. In fact, he just HAD to be nice to Frodo. I like Frodo, he's better than Sam.
