The reason its annoying on the KM is becuse you have to cut the rubber part to make it fit lol.
+1 to what PL said. The flavor is not affected imo, if anything its better. And I have several KM's with diffusers and its pretty easy to put a couple slits in the top of the diffuser to get it over the flair on the stem.
