Personally I use the Sigma 105 f2.8 for macro and am very pleased with it, I've also used the Sigma 50 macro which is equally good. The biggest plus of the longer focal length is that you don't need to get quite so close to the subject.
As others have said a macro lens can be used for other work, but may not do so well at range. Both the Sigma macro lenses that I've used have been great for doing portraits with.
