I have finally got my brisket to have a more beefy flavor using a variety of injections including beef stock/bouillon and even trying some beef marinades (strained so they don't clog the injector). I'd say give that a try.
For me no brisket will ever beat a good steak or even a mediocre steak. The flavor is just different.
