My preference is not using thee auto bidder. The reason is very simple, when you use the auto bidder, and you are overwhelmed by the number of bidders, you waste a large number of Tcredits when maybe the value of the item is not worth fighting for. By going the manual way, you have the chance to gauge what kind of bidders you are dealing with and so you can plan strategy depending on the bidding trend and safe more credits while winning big.
