I would always use wild sockeye if I wanted a nice fried slab of salmon. I never buy farmed fish of any kind and I always ask the question before I buy. Around here farmed seabass is common. Wild bass is much more expensive. I must confess to not being a fan of smoked salmon. I eat it when it's served up but I wonder what the fuss is about. It still feels like I'm eating raw fish. In Kefalonia last year I was miffed to see all the fish farm enclosures around the coast. I suppose most restaurants there that serve fish use farmed. If you ever go to Kefalonia, drop in at Ellie's restaurant in Fiskardo and have the kleftiko lamb. You'll be in heaven.
