The Limbo is for the traveler that wants an assurance that the corners of the piece will not become dented. The Limbo also has a "stronger" clasp system instead of the zipper system of the Salsa. The Limbo corners can be replaced if they are dented, something which cannot be done with the Salsa.

Tumi make a nice product however I doubt that they have the service support and design features of the Rimowa Salsa. The handle and wheel assemblies alone make the Rimowa stand out.
