I really like Cloudflare too and have all my domains with them, they take 0 fees as a registrar, so I get domains at the same price as the registry price + ICANN fee.
However one downside with choosing them is, you're effectively locked into their DNS, since they don't seem to expose the ability to set your own Nameservers, which is ok if you planned to use them for Authoritative DNS anyway.
