I think Sedo is more secure if you're using a registrar where they hold an account. If I ever sold a high value domain, I would insist on Sedo over Escrow also. I've heard too many stories about Escrow where the buyer gets the domain, only changes the email address in the contact info (to like a free Yahoo email) and claims they never recieved the domain. Since Escrow never actually takes control of the domain, it's hard for you to prove that the buyer got the domain. Escrow only attempts to verify the transfer after-the-fact through the Whois info... If the whois info hasn't been changed aside from a new email address, you have to attempt to prove that you sent it. Too much hassle in my opinion. For being Escrow.com, they certainly need to look up the definition of Escrow...
