I think if you just want a family use amount of milk than depending on family size a goat is probably sufficient. They are also easier to handle as far as size goes and are cheaper. If you want to sell a cow may be more worth your while.
Facilities also need to be considered. I know for my acreage I plan on getting goats but my fencing isn't goat safe, it's cow safe. So I'm going to have to fence before getting a goat. I also plan on having 2 goats and rotating breedings so the same goat isn't giving birth each year. Anyway, just what is going to work for me since I'm not planning on selling milk and only need 2 gallons for drinking and some excess for cheese and etc. a week.
Either way, good luck!
But they cost you up front. And particular animal still matters more than breed or species.
They don't give the quantity of milk goats or cows do but have 2xish the solids of cows milk.
They don't escape like goats do and like pasture better than goats.
They like are great weed eaters.
If you don't want to sheer, Katahdins are hair sheep who shed and some are almost as good milkers as dairy crosses (although they may not lactate as long). The Katahdins are much cheaper than dairy breeds. I have had no parasite issues with them if they rotate pastures.
They are very prone to dog and coyote attacks on the down side.

in my opinion - the choice of cows vs goats is generally answered by the forage available.
if you have mainly grasses - i would recommend cow(s)
if you have mainly browse (trees/brush) then i would recommend goats.
in your case i would recommend a cow(s)
hope that helps.
