PDFpen and PDFpenPro 11.1.1

FYI, I have PDFpen via Setapp and “Nuance Power PDF for Mac” via a recent Fujitsu ScanSnap iX1500 purchase bundled license code.
They have almost identical interfaces, as from my investigations they seem to both use the same Kofax backend. Wonder whether the Pro version of PDFpen does anything the Nuance doesn’t…?
