I had your very same doubt. What can I tell you after thinking on the matter a lot, is that they probably are equal if you consider all the pro and cons of both models (but my choice was between the two 1000) which are almost equal in price/quality. My final choice was mostly made based on my space, where the MH was best suited, and for the detachable driver that i placed outside the tent. But with no doubt they're both great for their prices, it depends on your needs.
Hope this helped someway, happy growing!
