Not exactly, but IIRC eBay puts seller reputation front and center, while Amazon greatly obscures it.
Amazon's focus on "product reputation" and near-total lack of emphasis on "seller reputation" also enables certain kinds of fraud (e.g. using inventory commingling to launder counterfeits, transferring ratings from one product to an entirely unrelated one by rewriting the listing).
