Not sure if you should upgrade to the latest iPhone?
Don’t worry, it is rather confusing but, hopefully the below table will give you a quick idea of the major differences.
If you hate tables, let me say this: If you have just upgraded to the iPhone 6, there is not a real reason to want to upgrade now, unless you really want the 3d touch and an improved camera.
It is interesting to note that the battery capacity on the 6s and 6s Plus is less than that of the 6 and 6 Plus
The RAM was also bumped up on the new 6s from 1GB to 2GB but, other than that, the differences are insignificant.
The Plus editions are huge monsters if you have small hands but, being blind and turning the screen curtain on will have the added benefit of extended battery life. The bigger screen will also make it easier to type if you are using Braille input methods and have huge fingers.
And now for the table:
