There are some people who maintain that the head shell connections used can be problematic, and may over time suffer from corrosion or poor contact.
Furthermore, individual cartridges may require slightly different setup, especially if they weigh much more/less, which is hard to accomplish with headshells but easy with wands (which retain their unique setup with respect to balance, etc.) For these reasons, wands are somewhat preferred.
