The i1Pro 3 family

Does it matter which model of the i1Pro 3 family I pick? I assume Publish would be a waste of money since the difference between that and Basic seem to be it's printer and scanner profiling capabilities, but what about the Plus and non-Plus model? The only difference there seems to be size of the aperture (non-Plus 4,5mm and Plus 8mm), does this make a difference in display readings? I would only use if for probe matching.

The 'Publish' package has unnecessary additional hardware.
And the 'Plus' is of no benefit for display calibration, and the wider aperture can actually cause less accuracy with low-light measurements.
