Can you substitute sardines with anchovies?

Sardines can replace anchovies, but they do not make for a great substitute. Sardines last longer than anchovies, but they don’t give the same taste as anchovies and will leave a fishy smell in the dish. Cooking anything with anchovies does not impart a fish-like odor to the dish but leaves a wonderful flavor.

Preferences can vary here. Its debatable if you see because each one varies in taste and nutrition
