Cloudfront allows you to map your S3 with both
- signed url's in case you want a session base files download
- default public files, for e.g. a static site.
You can also map a domain (sub-domain) to Cloudfront with a CNAME record and serve the files via your own domain.
Cloudfront distributions are also CDN based. This way you serve files local to the users location, thus increasing the speed of your site.
For lower to mid range traffic, cloudfront with s3 is cheaper as the network cost of cloudfront is cheaper. But for large network traffic, cloudfront cost can balloon very fast. But in those scenarios S3 costs are prohibitive too!
