Versioned Obsoletes are superior, because they occupy only a specific
EVR range of a package namespace. For your example of "gaim < 999:1",
you can reintroduce a package with the name "gaim" (suppose it's a
different piece of software) by giving it an EVR higher than 999:1.
On the contrary, the unversioned "Obsoletes: gaim" blocks re-entry
of a package with the name "gaim", regardless of its EVR.
