I purchase quite a few anthologies Genre and non-Genre and have always found the choice of story and their arrangement on the whole to be very good. I don't know which Editors or associated publishers you may be referring to but I'm referring to the likes of Victor Golancz, Penguin, Norton, Library of America, NYRB, Harvill Classics etc. My point being that those publishers that have a strong reputation for publishing quality fiction also I notice generally tend to have excellent editors at the helm of their anthologies. There are always exceptions but that is the trend I have noticed, including several radio interviews I have heard where Editors have discussed their rationale in choice and arrangement of stories.
