Shure MV88 vs. Zoom iQ7

Here is a sound comparison of two iPhone mics: The Shure MV88 and the Zoom iQ7. Currently, the MV88 costs about 50% more. I'm not sure if the sound difference is worth the higher price, but I still prefer the MV88. I like the Shure Motiv app that works with the MV88. Also, I have had a problem with the iQ7 disconnecting when shooting in the landscape orientation.
