I'd say both tools are useful, as each has different strengths and weaknesses. From one Universal Mesh figure to another, I'd say Clothes Converter is superior. But for converting between other non-Universal Mesh figures, Wardrobe Wizard wins. This image is a conversion of the FireDancer from RDNA to Jessi using Wardrobe Wizard. It was quick and relatively painless, though there are a couple of small problems with the bottom of the skirt, and I found that trying to convert the jewelry did not go too well. This took longer to render than it did to convert.
