It's not really lesser. I went from a 6 Plus down to a 6s. Still haven't noticed a change in resolution unless I hold my phone really up close and look for it on things like the serifs on text. The color and contrast are essentially the same. The extra keyboard buttons in landscape were never used, nor were the sidebars very useful in landscape as most third parties haven't even added support for it. The 6s usually benchmarks a little higher than the Plus because of the smaller screen—especially in graphics benchmarks. The only thing in my mind that might make the Plus better is OIS. I never noticed the benefit on my Plus, but the new one works for video which is more useful. So it depends if you record a ton of video, especially when walking around a lot. The battery is better in the Plus, but the 6s should give you full day battery life. After a few months the Plus usually couldn't make it through the second day all the way, so I needed to charge it every day anyway. But if you heavily use it all day then the Plus battery will be worth it.
