Yes, they still exist! In my limited experience the milk does taste better but I think it's because of management, not genetics.

The "get big or get out" Holsteins of conventional dairying will produce themselves to death. That is, they'll make milk even at the expense of their own bodies. To handle that, they need to be fed very intensive grain-based diets (corn and soy). Otherwise they'd waste away.

But low-input cows can produce milk on grass-based diets without wasting away. Grass milk is healthier (https://extension.umn.edu/pasture-based-dairy/grass-fed-cows...) and in my experience, tastier, too!
