Hi there,
Business degrees are by far the most difficult to assess and for good reason! There are a few factors that play in. Firstly, the prestige of the school itself. Secondly, the concentration. So Finance at a reputable program would generally rank a little higher than, say, operations.
Overall, however, business degrees fall, in most cases, below most engineering schools but there are a lot of overlaps and exceptions. So a business degree from a top 10 undergrad business program would outrank engineering at a #40 but a business degree from a top 10 would be considered slightly easier than a top 10 engineering degree. There's really no black and white answer to this unfortunately.
I hope this helps somewhat though. If you have other questions or want to delve into this a little more, don't hesitate to ask!
