According to Chaldean Catholic Patriarch Louis Raphael Sako:
But if you're talking about which was worse for people in general (and not just Christians). I think the Mongols were worse than ISIS. At least based on what I remember from reading Empire of the Steppes one year ago.
The head of Iraq's largest church said on Sunday that Islamic State militants who drove Christians out of Mosul were worse than Mongol leader Genghis Khan and his grandson Hulagu who ransacked medieval Baghdad.Maybe he is right, at least if you're just measuring which was worse for Christians. Thanks to Nestorian Christian missionaries who went deep into Asia in the 7th Century, a significant number of the Mongols and Turkic tribes who invaded the Middle East were Christian. Doquz Khatun, the wife of Hulagu was Christian, and she is credited with sparing the Christians when the Mongols sacked Baghdad.

Not that I'm saying ISIS is less than awful! It's just that the Mongol hordes are hard to beat, atrocity-wise.
