The difference on the surface is in pricing:

KMS: $1/key/month, $0.03/10,000 requests
Secrets Manager: $0.40/secret/month, $0.05/10,000 requests

But the practical difference is Secrets Manager integration into services like RDS, Redshift, and DocumentDB, where rotating the secret will automatically update the corresponding passwords in the database.

yep. slightly more expensive, but i find the integration and rotation very very useful.
