There is no substitute. Wild caught salmon is the nutritious one. Being wild caught, and never tampered with from human made feed, it has a firmer flesh and is less fatty. BUT it's more nutritious.

The #1 complaint about Wild Salmon, is that its too firm/dry. The reason is, that you have to cook it with care. Atlantic salmon has a tremendous amount of fat that allows the fish to be pan fried at any heat for any amount of time, and it will still be oily and flakey.

Once you know how to handle a wild salmon, and realize the health benefits and appreciate the taste, you’ll not go back to Atlantic Salmon.

Handle with care. Wild salmon can have a raw middle section. Low heat, braised, or ‘off flame/indirect’ cooking are the best options. (Planked wild salmon, topped with lemon slices and seafood spices, delish)
