Hard to say what's better. I never used an A/S with the mallards. Sometimes my face felt very dry after a shave but glassy smooth. Both are great. The one thing about omnibus I don't like- the soap residue is tough to rinse off whereas mallard is much easier to clean off. With omnibus, even after I rinse my brushes pretty well the next day I can see the soap residue on the hairs. I like them both and have no opinion on which is better.I’m curious - do you find the post-shave of the Mallard to be as good as B&M Omnibus?
