4 or 4.7 or 5.5-inches — What's the perfect iPhone 6 size for you?

If Apple holds to pattern the iPhone 6 will be coming out way this fall, and if rumors are true, there'll be not only a larger size, but two larger sizes to choose from. I've been writing about a bigger iPhone for years, and why I think it makes sense for Apple to do it this year. But what happens when it's a reality? What happens when you walk into an Apple Store and see a 4-inch, 4.7-inch, and 5.5-inch iPhone all sitting on the table. Which one do you choose?

To keep things simple, let's imagine the iPhone 6 feature set is locked. You get the same camera, sensors, radios, colors, finishes, materials, and other specs regardless of which size you choose. You're picking based on display size and display size alone.

So what will it be? 4-inches to maintain maximum one-handed-ease-of-use and pocket-ability? 4.7-inches to strike the best balance of small enough to hold, big enough to enjoy? Or 5.5-inches so you basically have no reason to carry around a small tablet with your for mobile computing? What's the perfect iPhone 6 size for you?
