History HL is a delight and people grossly overestimate its difficulty level. Yes, less people get 7s in History, but that's more because people just don't study History correctly or don't develop the correct essay writing skills in the IB. I don't blame students for that, I blame their teachers for not equipping them in the way they need to be.
Just FYI, B&M is not looked upon favourable by most Unis, if you take it at SL, it won't make any difference, but I would think twice about taking it at HL. I spoke to various representatives from Oxford and referred to the LSE prospectus when I was in the IB and they did state that Business Studies was included in their non-preferred subjects list and they would discount it if a prospective student had taken it as one of his/her main subjects (which for IB students translates to HL). I also spoke to a representative from UPenn and she told me that they would understand why a student takes B&M if they're interested, but they would wonder why B&M if an Economics course is available as well.
Also, if a student takes both B&M and Economics at HL because they want to be Business students at Uni, this adversely affects them at US Unis because it shows that they haven't much variety and diversity in their subject choices as compared to others (however this was the opinion of one Uni Rep, I'm sure some other admissions officers would speak differently).
My personal opinion, stick with History and don't be afraid of the challenge. If you're afraid of taking on a challenge, then perhaps you should rethink if the IB is really for you at all.
But if B&M is what you think you will find more interesting, then knowing the potential pitfalls, you should make that decision.
Best of luck,
