@Peter_70, Welcome to the HP Support Community!
Both these printers belong to the Photosmart series and hence are good for printing and scanning photos. However, both these printers are pretty old and HP has stopped its manufacturing.
You will be the better person to decide which one you want to keep as you have used them as there is no much difference in its specifications.
Hope this helps! Keep me posted.
