I have compared both and personally I like Jonathan's version. Of course, I am not an expert. I do not have any collection of high quality Urdu documents. I have only seen Mirza Ghalib's manuscript in his museum in New Delhi and some Urdu documents in the museum in LaL Qila. My knowledge of Urdu is very weak. Spoken Urdu is basically the same language as Hindi so that I can listen to BBC Urdu and understand almost everything but reading is difficult for me and I know nothing about calligraphy. It will take me hours to read the sample text, I can only recognize from the title that it is the Universal Declaration of Human Rights. Anyway, the larger interword spaces do not help me toread the text.
As an example I am attaching the text from the Jama Masjid in New Delhi. Look at the beginning of the first line. There is a considerable space between آ and پ although آپ is a single word. The interword space between آپ and جامع is smalle that the space in the middle of جامع and there is almost no space between جامع and مسجد. There is no space between پر and زیارت but I still can see the words. In the third line the largest space is in the middle of پرکشش. Of course, it helped me to see the same text in Devanagari, I would probably be unable to read the Urdu text without it.
