I'm quite the carnivore, and have not really noticed a different taste to beef. There are some over all apearance differences though, such as the way the ground beef or "mince" is, well, ground or minced.
As for steaks and roasts, I think they same.
Sausage, however, I find very different, and "American" bacon is hard to find. Yes, they have streaky bacon, but I feel it is too salty for my palate...
