What was the primary feature that distinguished the Mughal Empire from the Ottomans?
I think the main feature or difference between the Mughals in India and the Ottomans in Turkey/Near East was that the Mughals had perforce to be much more tolerant of other religions/points of view than their own (i.e. Islam).
The Ottomans presided over a Muslim majority within their own domains; whereas the Mughals (and earlier Muslim Sultans of Delhi), were a religious minority in South Asia where Hindus, Muslims, Christians, Buddhists, Sikhs, Jains etc, all co existed. Of course, the Ottomans were still comparatively more tolerant of religious minorities vis a vis European rulers at the time, but they did not have to face the same circumstances the Mughals did.
This position of broad Mughal tolerance lasted till the time of Aurangzeb Alamgir the 6th Great Mughal, who proved to be intolerant and thereafter the Mughal decline began.
