A lot of the advantages are pretty subjective, and I'm biased (I didn't post this, by the way, I just learned about it via twitter).
Housingmaps is great, and was probably the inspiration for all these sites. The reasons I wrote my own were its limited selection and inflexible filters, which were pretty painful to use in my search.
Hotpads was around, but I didn't like it very much when I started this. I think it used to be more big buildings/complexes, and I don't like the flash-based map (I'm on a mac). It's perfectly usable, though. If you give both a try, I'd love to get your impressions.
