Avplan and Ozrunways are infinitely more feature rich than a Garmin Aera660.
I have all three of the above, and for me Avplan and Ozrunways are both equally good, Garmin very much less so.
With Ozrunways/Avplan can avoid buying and carrying paper maps, although a back up paper map is not a bad idea.
Ipad only issues for me is occassionally sunlight readability difficult (and that is fixed by angling/moving ipad), and shutdown due ipad getting too hot.
The only area that the Garmin is better is sunlight visibility, and it does not seem to shut down in heat (I have had ipad shut down once for short time when in direct sun and mounted on thigh so no air gets to back of ipad - ipad restarted after 5 mins held up so air vent blowing on back of ipad).
So ipad or android for first pref, and a dedicated GPS as a backup if you want.
And yes, before someone pitches in, we should not become reliant on GPS.
