I use both. A soap bowl lasts quite long and to add some variety I always have one or two cream tubes in use. Floris and D.R. Harris are very good quality and have a variety of fragrances. I would try ToOBS, but the sales assistants in their Jermyn Street store are so unfriendly that I rather stick to my two favourite brands.
Both very good, Arlington being my favorite DR Harris soap. I wish Floris made a soap using the Santal scent. Penhaligon's came out with their reformulated soaps and they've received great reviews. My favorites are Acqua Di Parma, Santa Maria Novella, Castle Forbes and vintage Penhaligon. I really want to try TOBS grapefruit and coconut this summer.
Can you get TOBS somewhere other than the TOBS store?
