Not gonna lie, I don't know to much about Bohr as Ive only heard his name in passing a few times over the years during my random readings. I based my answer on my knowledge of Hawking, where his research led, and your question.
Now, for practical knowledge that pays off in tangible day to day uses Bohr may be the more important person (I have to do some reading to figure out an opinion on that one) but for overall expansion of our understanding of the universe as a whole it's kinda hard to beat Hawking.
