Dried chilies? Actually a thing. They say the flavor changes a bit when dried, and you use them differently.
Fresh chilies are juicy, and are used for salsa, salads, sandwiches, and stir fry. Dried chilies can be put in chili, soup, or marinade to make it spicier, or smoked and crushed to make flakes, powder, or spice mix.
Also, dried ones are preserved and can be revived with water. They can last for years if done right, making them suitable for stashes.
