The sole difference being "NetFlow is Cisco proprietary, sFlow is not" isn't exactly correct.

NetFlow originally started out as Cisco proprietary, but kind of went the same way as GRE or EIGRP. Since NetFlow v5 it has been implemented and supported on other vendors' hardware.

The main difference between NetFlow and sFlow is that NetFlow is restricted to IP only, whereas sFlow has the ability sample everything (network layer independent).

EDIT: The above appears to be no longer correct (at least as of the IPFIX standard). I've found the following blog post (warning: seems to be an "sflow" specific URL, so take it with a grain of salt if you wish) does a pretty good job of outlining the differences between the IPFIX spec and sFlow
