Love is that which makes us feel good about ourselves, the sense that something, someone, some activity validates and gives meaning to our existence. One can love a job, a sport, a person, family, country, a philosophy/deity. Some of this is an argument about semantics, but I believe this is the common thread to what people perceive as the meaning of the word. The logical consequence is that "Love" is then the most important thing (or things) in ones life. But humans are psychologically messy. One can love things to different degrees as they are more or less important to the core of one's sense of worth. Being empathetic and giving can match one's sense of self worth and build it on a broader/stronger foundation than say sports or a job. So one could argue that is "better" in some sense.
