CloudFront is also a pretty inferior product in the CDN marketplace. Why do you think Amazon's retail business signed a huge contract with Fastly to be their primary CDN for all mission critical retail images? CloudFront sucks. Not competitive on price, features, performance or anything other than "we already pay AWS so might as well use it".
One advantage of CloudFront is support for uploading large files (5GB+) to the origin server. CDNs tend to enforce a low size limit for uploads. It’s probably an uncommon use case, but the reduced client-side latency is nice for customers who are far away from the origin.
