Both arm types are designed to deal with tracking error. Both work, but the S arm will always have more mass (bad), and counter- balancing the arm will not make mass go away. DD was made popular in the 70s and 80s by companies based in japan. Their marketing positioned belt-drive as old fashioned. In reality, belts work better (with a hi-mass platter). The DD motors would tend to 'hunt' for the correct speed with their Phase Lock Loop feedback system.

Most audiophile tables now are belt drive with a straight arm. If you are looking for a good entry model, check out:
