It chatters all over the place and makes you think you are destroying the AF-S motor on the lens which you probably are and works relatively poorly for AF. If you want to use it in MF mode it's superior to the others you mentioned since it passes through EXIF data from the lens which can be useful for lens correction in post not to mention in cataloging by focal length if you care about that sort of thing.
As for the Novoflex, there are two ways to deal with the click less aperture, one is to simply open it all the way and then watch your exposure readout in the camera as you stop down, each stop change in exposure reading equals one full f-stop. I did that initially and then after noticing that it's relatively consistent from lens to lens just put a sticker on the adapter to indicate aperture marks. The Fotodiox adapter by the way does have clicked stops.
