It all depends on how you are using your products, if you do exactly what it says on the tin I would suspect you will get the same results, but with MS you do get the added benefits of no residue so less rinsing, no odour, and safe as cleaning products go (can you still drink it?)
Domestically I think it's still King, as I use the wool safe version and it's fine to apply protector immediately after cleaning and safe on most awkward items.
