I would be very surprised if there were any such thing as a "consensus". A number of good products exist; they work in different ways, have different features and different people would have different preferences depending on their taste in GUIs and their perception of results relative to their purposes and expectations. The most serious way of making a choice is not to be concerned about any kind of consensus, but to download their free trials, test them and see which, if any you would prefer over what Lr does. Beware of whether you need to create a pixel based image to use them, or whether they can be used directly on the raw files as Lr plugins not needing permanent conversion - this would be a consideration for those who prefer a complete workflow within the raw image format.
