I used to have burping of fishy taste with some fish oils but haven't had any problem at all with Nordic Naturals Ultimate Omega. It has a lemony flavor but I don't usually even taste that since it's a gel capsule. Also good, but slightly larger is Life Extension Foundation's Super Omega-3 EPA/DHA with Sesame Lignans and Olive Fruit Extract. My husband buys his fish oil at WalMart and most cause flavored burps except Spring Valley Enteric Coated Omega 3 Fish Oil (with No fishy aftertaste written on the label). Is there a difference in quality? There is a huge difference in price.
