Both realtors ultimately work for the seller. That's who pays the commission. In fact, the buyers agent's comission is paid by the seller's agent, so really, the buyers agent works for the sellers agent who works for the seller.

Buyers agents are good to help you find a property. When it gets down to the deal itself, both realtors will try to make the deal happen and neither are really responsible for representing your best interests (especially if your best interest is not buying the property). They simply facilitate a standard purchase contract.

A single agent scenario is probably worse for the seller, as their agent will be very motivated to get the deal done with a particular buyer.

Either way, I don't think it makes much difference. In theory you should be able to save more money using the seller's agent, but you might have better luck getting someone to negotiate for you. All depends on your level of comfort with negotiations etc...
