Freeze-drying retains MOST of the food's flavor and nutrition, but not all. The frozen stuff is more natural and takes no time to rehydrate. I have read that freeze dried foods can cause some internal damage if a fish eats it before it rehydrates - this could be hogwash.
Anyway, bloodworms are actually midge larvae (mosquito-like insects) instead of worms. Live foods such as larvae and worms are nutritious, and they really should be supplemented to your fishes' diets. However they are also very fatty and should not be the sole food, nor should they be fed every day to your fish. But they love 'em and it helps bring out the color very nicely!
