Both cuts of beef are equally as tasty. In general though, a tenderloin has a lot less fat and it’s much more tender. It’s a delicious meat and it can feed large groups much more easily. It’s also very simple to carve, and it can be cooked with a bunch of different rubs to really bring out the flavor.
On the other hand, you are going to be spending a lot less money if you buy a prime rib. In addition to that, you will get a much stronger beef flavor, which makes it perfect for things like a Christmas roast! The presentation will also be much nicer usually, and it’s easier to cook too. Pretty much anyone can cook a delicious prime rib if they know what they are doing. Regardless of what you choose, you can get a delicious tenderloin or prime rib from websites such as Crowd Cow.
