My experience with Cloudflare R2 has not been great. It has been extremely buggy and we have often seen throttling with Cloudflare during peak times.
The Middle East PoPs also don't offer great performance and often get switched randomly to different countries which breaks audio streams.
The cost may be lower, but running our own CDN offers a good balance of cost and control.
So we only use Cloudflare for basic DNS services.
