Normalmap baking hi to lo poly

Hi,

I am having some issues with baking normalmaps from hi poly to lo poly mesh.

I get the best results with no artifacts when using a lo poly version with smooth normals on for example a box shaped object. However this results in texture gradients on the normal map on flat surfaces.

Searching around on modelling forums, it is generally recommended to not use this approach of smooth normals. Looking at this page however it seems Unity actually recommends this:

Any thoughts on this?
