What's the best material for a soap dish that keeps soap dry?

Across the reviewers we read, silicone with a sloped or ridged drain pattern and natural teak with a slatted/heightened base get the most consistent praise for keeping bars dry. Ceramic looks the best on a vanity but only drains well when the design includes a tilted or leaf-shaped channel. Specialist subreddits including r/soapmaking and r/BuyItForLife repeatedly warn that flat ceramic and diatomaceous-earth dishes turn into soggy mush traps.
