It's all incremental benefit. You get some additional situational awareness from the app you're using, you get some more with ADSB receiver and you get some more with your eyes out the window and some more with your ears on the radio. Add it all together...
You'd also be surprised how many operators are using them...All the HEMS rotary wings in Victoria, the bank runners, RAAus a/c, private a/c, RFDS...

It would be far more useful to have live SSR and ADSB feeds being downloadable to these apps as it is on websites like flightaware.
You can have that too on either app for around USD$100, see
