We actually switched FROM cloudflare TO cloudinary. CF seemed cheaper, but we found the service, the dashboard, and the service to be wildly erratic. Price went all over the place, we'd get double billed, the dashboard would stop working for a week.
Maybe Cloudinary is more expensive (though not by a lot for our use case) but I can say that nobody has had to log in or think about it for months. The thing just works.
Most of the CF add-on services seem to be hobby-quality. We used to use their video stream/encoding service too but have since switched to another more robust platform.
I've never used imgix but I find Cloudinary (and specifically the Media Optimizer product) to be extremely reliable, reasonably priced, and as close to zero-maintenance as a thing can be.
