Red meat is higher in cholesterol and fat...from what I have heard...most of us probably don't remember eating "good" Beef.
I have not tried the grass fed beef products...they are very expensive but I think I will try it some time to see what difference it makes.
My initial guess is that it will be leaner and won't have that juicey fatty flavor...like a ribeye that is my favorite.
I have had filets before and don't care for them...know that sounds crazy...
Oh another reason to avoid ground beef is the higher risk of contamination from the grinding of the beef.
Every surface that comes into contact with a blade runs the risk of contamination.
So with ground beef.... all of it runs that risk.
This is why hamburgers should be cooked well done thru out...and why a cut of beef can be Medium Rare or other , as long as you cook the sides that were exposed to the blade.... Makes sense.
