Cabezon and Halibut are my personal favorites. Both are a little hard to come by. Lingcod are a great eating fish, and I would compare them to halibut, but much easier to catch, including a wider area in the PNW, and not as highly restricted for season and limits. They are like halibut or rockfish in that they don't have a strong taste of their own, and take seasoning well. I like NE Brazil style with coconut milk and curry. The flesh is sometimes green or blue, apparently from eating octopi and squid, but this doesn't seem to affect their taste. Tastes are obviously personal, and I really don't care for black cod or king salmon as much because they are so fatty and already have a strong taste profile. However, I would enjoy them if set in front of me.
