In my opinion there is no answer to this question. Both scenarios are subject to an equal amount of risk. The most important thing is securing the workstation itself. If done properly, the risks of staying connected or re-connecting are self-canceling. Do what is most convenient for you, just make sure your workstation is as secure as it can be.
