That algorithmic, discovery-driven distribution is why practitioners treat Reels as a prospecting and awareness surface. Stories, by contrast, appears between the organic stories of accounts a person already follows, so it tends to touch warmer audiences.

At the same time, always add captions or on-screen text, because some viewers will still watch muted and captions protect comprehension either way.
