Not sure why parent was voted down but it's true. The inputs have a lot to do with the outputs. Grass fed beef has its advantages in many ways, but grain fed does as well. Generally, you see a nice balance when a cow is grass fed most its life and then fed grain the last couple months to fatten it up.

Aaron Franklin talks about this in his book and mentions he only uses grain fed beef for BBQ. Grass fed briskets just aren't as tasty and lack the marbling of a prime Angus brisket, in his opinion. But the guy has cooked over 100 briskets each day for over a decade so I imagine it carries some weight.

In my preference for steaks, I like both. But it depends on the cut. For a Ribeye I'll take the grain fed. For a filet I'll take grass.

Here's the thing, "grass fed" beef is still fed grain. You're looking for "grass finished", which is quite rare.
