Aurora is a great mouse! I've been using it since I got it from Massdrop. I added little weight from Pure***** Valor's weight cartridge and changed cable. Its damn perfect for me after few modification. Sensor is good as well, I don't know why tracking quality is not enough for you. Re to your question there is only mouse with good sensor is Logitech G303 (at least on the paper) Rest of them you just have to try and see if they are good enough.
