When it comes to the very best midranges, people get properly tribal about which one is the best. So the hot take is whether any disc can rightly topple the Buzzz, and I reckon the Emac Truth has a fair claim. Obviously, they are neck and neck on just about every measure - stability, distance, handfeel, etc. - but the edge for me is what happens to the disc over time, and for a variety of plastic types (except perhaps some of the super-stiff Ledgestone drops which I have never tried but are by reputation some of the toughest plastic ever used by Discraft) the Buzzz loses its reliability faster than the EMT. The danger for me with the neutral midrange is being flipped over, especially on downhill drives where the wind just loves to shove glidey discs sideways. And so you really want your neutral midrange which you have invested hundreds of throws beating it in to get it flying "just so" to stay reliable for as long as possible, and the Fuzion or Fuzion-X plastic just keeps that window open for much longer than the Discraft Z plastic and ESP. It may even be the shape of the disc that contributes to the stability because I have a Prime EMT which is dented all to hell and still flies properly!
