What's the best mold/mildew resistant caulking for showers?

All your typical name brands that tout mildew resistant will work fine especially the silicone based. What ruins the mildew resistance of any company’s product is the applicator meaning the person applying it. For some reason most people in order to get a clean smooth looking finish wet their finger by spitting on it and then drawing it across the newly applied sealer. Well they just embedded a whole mouth full of germs for mildew, mold and fungus to build and thrive on. Hot dog, best laid plans of mice & men ruined by human spittle. Keep your finger out of your mouth use a container of distilled water to wet your finger if you must and stop laying the foundation for mold, mildew and of course fungus. You’ll have a spit free application.
