Although you have accepted a "solution", simply having a table to compare capabilities is only half the story. Because it is simply a comparison table, too many of the Prime capabilities don't provide details about any item's behavior that can be missing in Prime that exist in Mathcad 15...like the way in which you have controls over elements of a plot, or the amount of points you can plot, etc., can paint a very different image of the true comparison. There are clearly aspects that are improved, but some significant capabilities are "watered-down" or missing...a table won't shed light on where those are. I hope PTC will address these BEFORE they sunset access to Mathcad 15 in another 3 1/2 years. We would like to have at least a year (or more) to convert files over with 2D & 3D plots that don't have labels and titles stripped, and collapsible regions that can also be expanded and shrunk WHILE locked, etc. This forum has identified a fairly substantial list of functions, and behaviors, that have not been addressed.
