They taste pretty good to me - can't really tell the difference between these and the Ocean brand ones. At the end of the day they're probably fished by the same boats and they're all canned in Thailand - it's a very simple product so there's not much room for variety.
No Name Canned Tuna was my tuna of choice when I was a university student simply because of the price. Since getting into the work force, I started buying Ocean's brand at Costco. I find the biggest difference to be quantity of tuna versus water. The Costco tuna is 184 grams with water whereas these No Name tuna cans are 170 grams with water. As the can clearly indicates, there's about 50 grams of water in the No Name leaving about 120 grams of tuna per can. I find there is significantly less water in the Ocean's brand at Costco resulting in a larger amount of actual tuna per can for Ocean's brand from Costco as compared to No Name brand.
