Feeding methods are different: grain-fed beef refers to beef with grain as the main feed, and Angus beef refers to beef raised by Angus cattle breed.

The meat quality is different: because a large number of grains are taken in the feeding process, the meat quality of beef raised by grains is tender and smooth, and the taste is softer. On the other hand, Angus beef is more tender and delicious because of the characteristics of Angus cattle breeds.
