The edit screen of #Wikipedia' is similar to the standard screen of #Wikidata: it is ugly and it does not present the data well. Look for instance at the two screen shots. The same data about the "office held" by Mohammed V of Morocco is available in both screen shots.
The screen shot above is the standard screen of Wikidata for Mohamed V. The screen shot below is the same data formatted by "reasonator".
There are issues with the reasonator. When you compare the data you will miss the second term in office as Sultan of Morocco. There are other bits of information that are formatted in a weird way. But that is not really important. What is important is that proof of concept tools like the reasonator and the geneawiki motivate me to enrich an item with statements.
PS I really got into the reasonator when I learned how to add a picture.
