My 2 cents worth.
I have used OzRunways, ForeFlight and Jepp FD Pro X.
For domestic use, Oz Runways is best IMHO. It's just better set up for Oz domestic needs. Support is great too, they even respond on weekends.
ForeFlight is also good and would be preferred if doing anything outside Oz or if you need your EFB to communicate with say, Garmin G1000 NXi avionics (wifi connection). App has some similar functions/input method to JEPP FD Pro.
Jepp FD Pro. Jepp prices! for airliners.
