I use the 796 and have off and on tried ADSB on the iPad. I keep going back to the 796. The Wx on it has always been reliable plus it has many more features (even a semi-synthetic vision) and I do like to listen to the XM on long flights. I also like that it pulls power from the plane and has an extended battery so is a good back-up if there was an issue. I also use Foreflight on an iPad and have a mini-iPad velcroed over my MX20 (has lines in it so I use it as a back-up). I do like to run the Xavion app on the mini which gives me an additional sense of security in the case of engine out. The big drawback for me with the iPads have been battery life and any chargers I have used in the plane created static on the radio (sometimes severe). I have thought about the stratus too because I run Foreflight and like the additional backup for the AI. My two cents.
