Also wanted to mention, it is very personal whether somebody wants a box shape or a tube shape.
It's all psychological, I used to like box shapes, but now they just don't "feel right" to me and I am back to cylindrical shaped stuff.

I would put one of each in your SIL's hands or better yet take them to a B&M to see, touch, feel some of the products
