I dislike Odin and Atlas. They sounds very... try-hard uber-masculine. I love Echo. I love girls names ending in -o... (although with this particular one, because it's also a word, I would be more inclined to use it as a middle or on a pet) and I am a pretentious geek as other comments have rightfully assumed. That's completely spot-on.
