I don't know your exact use case. If you tell us more, we can help you better. We used Vimeo to serve an approx 30 sec video to about a million viewers a month and it was great. We noticed some minor downtime (few minutes at a time) but that was acceptable to us. Cloudflare might be more reliable, not sure? Network infra is their bread and butter, and I tremendously admire them, but their streaming offering was overkill for our basic needs. Ultimately their target markets are different. Cloudflare is an infrastructure company targeting devops teams, Vimeo targets small-to-medium content-driven businesses who don't want to do devops. Probably Vimeo's control panel is easier to use for content producers, whereas Cloudflare might have better APIs for devops types? At a few thousand viewers a month, it's a pretty trivial use case and either company (or any other professional video host) would probably be just fine. It comes down to your own pipeline/production or business needs, probably. As for being able to switch from one host to another, hopefully you're promoting a landing page of some sort and not a direct video URL. In that case you should be able to switch video providers at any time without interruption. Just keep the old version up alongside the new one for a few days, in case anyone has the page cached.
