I'm not sure I've ever heard that aspect of it debated. I've only heard "Is it worth 3 times as much to have my radio talk to me?", or "I don't need a color picture of my jet", or "Futaba programming just doesn't make sense", but I guess your perception is your reality & if you feel your DX18 is the technologically superior choice, then rock on, but IMO comparing them side by side to the average human would linearly be like comparing a standard phone to a smart phone.
Although I must say, some of those standard phones make VERY clear calls... Gets the job done for cheaper
