this is the primary reason I prefer to use Moniker's escrow service.
Better hope the buyer isn't paying from a hacked PayPal account or a bogus check, etc.
Because Moniker can potentially,
sometime well after the sale, take the domain back! NO other major escrow service, I'm aware of, will do that, but Moniker potentially can. Beware! To be fair, the odds of that happening are small, but not zero.
Escrow.com and Sedo escrow assume the risk of accepting PayPal, etc and guarantees the funds released to the seller is free and clear.
In short, Moniker is not a true escrow, since they don't guarantee the funds released to seller; may attempt to take the domain back
after the sale.
Sedo escrow is very good, though the speed can be slow depending on the TLD (some require more work, such as .co.uk to do right) and responsiveness / knowledge of the buyer and seller. Ie. if one of the parties makes a little mistake / overlooks a step, it sometimes add much delay, as in weeks+, to the escrow.
EscrowDNS I don't know enough about, but appears to have good reviews; they hold both domain and funds like Sedo escrow does.
In my view, escrow.com is best suited to transactions in which both buyer and seller already have some trust of each other, and seek to use escrow.com for a little extra security / add structure to the sale; moving the sale process forward in a timely manner.
