What seems like a better chocolate cake recipe?

The 1st option, Its a fact that coffee brings out chocolate in cooking also sour cream or if you dont have that mayo makes a cake very moist. Im not sure about the cream of tarter I would amit that...Im sure it wont make a difference, but the 2nd option uses 5 eggs and buttermilk...thats alot of eggs and buttermilk might leave the cake with an aftertaste. Milk is usually not needed when making a cake.
