It's the same operating system, it's just which phone you'd prefer.

I'm also going to point out the larger screen as the main difference. I put OS6 on my boyfriend's 9700. He loves it and it functions almost identically, however his icons are minuscule in comparison to mine, and it looks a little cramped on the home screen. He finds navigating easy, while I am used the torch and being able to pinch/move/swipe with my fingers across the screen. Using the trackpad to navigate is frustrating for me, but if you've never had a Torch, you'd never notice.
