I am not sure of the Dakota Kit but the Smith Kit is very complete. It does not include AN hardware but all the hard stuff is there. The wings have flaps, ailerons, fuel tanks, pulleys are installed etc. All you need for the wings are your strobes, landing lights and pitot tube.
The fuselage has tail feathers, tail brace wires, seats, cowling, windshield, control cables, boot cowl, new Scott tail wheel, wheels and brakes etc. If this is not included in the other kit it will add to the cost fast. Be sure you compare apples to apples.
Quality is outstanding as is the integrity, honesty and helpfulness of the Smiths.
Just some thoughts
