Mark, Both are good. To me, it comes down to versatility. I use an iFly 720 and also run the iFly software on my 7" Android. Both teh iFlly and Android talk to my Skyguard ADS-B gear at the same time and are capable of talking to a lot of different ADS-B equipment. With Foreflight, you are pretty much locked into Stratus as yoru ADS-B source, although a couple of other units claim to talk to ForeFlight.
Since I dont' have an iPad, I am assuming the iPad function is similar if not identical to my use of the android. Running iFly on the Android, it uses the 3g/4g network to grab a nationwide weather snapshot when I bring up iFly, so I have a current overlay of of nationwide NexRad radar as well as every AWOS/METAR/TAF/Winds Aloft report nationwide. Without ADS-B, the 3g/4g network will update the weather whenever you are in range of a cell tower, which is often a limitation of altitude as Roger describes for his use of Foreflight. With ADS-B, as soon as I turn on the ADS-B unit, the Android connects to the ADS-B WiFi and shuts down the 3G/4G network. From that point forward, I get the local NexRad radar overlay updated at 3 minute intervals, METAR/TAF/Winds updated at hourly intervals or less and a traffic overlay. I think you will find the functionality to be similar. It's just a matter or preference. I stick with iFly because they are willing to support a large number of ADS-B units, while Foreflight seems to be married only to Stratus. I prefer not to be locked into a single vender. Also, if you are already paying for iFly, adding on the iPad only costs another $20/yr. But I think you will find that both will allow you a 30 day free test drive, so download one and test drive it for a month, then download the other and test drive it and make your own decision. While you're doing that, you may also want to evaluate WingX and FlyQ. All of them are popular and all work well. As much as anything, it has to do with comfort level and preference for how things are displayed. Also, for those interested in an inexpensive ADS-B In solution, there is a lot of buzz on the EAA web site about building an ADS-B weather and traffic receiver for $120 using Raspberry Pi. I have a good friend that is currently struggling his way through the build, so will probably get to take a close up look at it soon.
