I've made the switch from the 6 Plus to the 6S. I didn't think I found the 6 Plus difficult or awkward to use until I started using my regular 6S. I'm able to navigate around and type on the keyboard a lot faster and more comfortably on the 6S. I'm not bashing the 6 Plus, I think its a great phone and loved having it for a year, the screen definitely looks a lot nicer and its going to take me a while to get used to the 6S screen and battery life. Over all I don't think I regret my decision, i'm actually surprised at how quickly i'm adapting to the smaller phone, I don't find it too limiting when browsing safari and watching videos.
