On a creaminess scale of 1-10 , tallow is about a 5 with good moisturizing properties. This, at least on paper, is about the same level of creaminess as palm oil, or shea butter. Stearic acid, which is the primary ingredient of MdC, for example, rates at around 9 for creaminess. Obviously, there's a lot of other ingredients in shaving soaps which also contribute to its performance (or lack thereof). The ratios of those ingredients as well as preparation procedures, curing and other factors contribute to the quality of the final product. There are many wonderful tallow based soaps. I believe my personal favorites are Tabac and the B&M soaps. There are also some that don't measure up. Likewise, there are many top-tier soaps that don't have a speck of tallow in them. I guess what I'm saying is the magic isn't found in just one ingredient, but rather the sum of the parts plus expert crafting -- just like a great martini.
