I Ask You: How Should I Produce an iPhone vs LG Camera Comparison?

I NEED YOUR HELP!
I want to do a video quality showdown between the iPhone 6 and the LG G Flex 2, similar to the recent LG vs Nokia video we just published. Now, I think you should always produce the highest quality samples that a phone can shoot, but that means 1080p video on the iPhone and UHD video on the G Flex 2. I don’t want to produce four different videos to compare these two phones, so what makes the most sense for a SINGLE comparison video?

I’m taking this poll VERY seriously as whatever the general winner is here, will influence how I shoot and produce a comparison video. These videos often take me a couple DAYS to shoot and edit. Beyond just voting, comments and sharing will be GREATLY appreciated, as I want this to be as professional a comparison as I am able to create.
