It is not better than direct printing, but for most art could be essentially as good. Of course, pressing the transfer to the garment is another point at which things can go wrong if not done correctly. And my understanding is that transfers eventually age and won't press correctly after some point, so you wouldn't want to take years to use them up.
The main point of transfers is that you do not commit one to a particular style/size/color of shirt until you have an order for that specific combination. So you have an upfront investment in transfers, but not a dozen prints on small red women's tank tops that may never sell.
