It does't matter, The scenario was to get a Plus to try it during one's everyday experience. Once folks get the 6 and the return period is up, well ...
Trying the Plus in store yielded nothing but what most folks owning the 6 say about it, it is too big. BUT trying it for awhile, you get more use to it. It doesn't change the size of it obviously but one is better able to see if it could be an alternative to go with over the 6. If not, well sayonara. If so, well you return it and get the right carrier, storage and color in the future and with the current demand it may be actually easier to exchange it over someone looking to buy it.
And one cannot carry and change into different shirts and pants in a store and personally I'm not going back multiple times. And do everything you want to do with it either. 🙂
