BSBA at Olin vs double majoring in Olin from Art&Sci

Is there any difference in getting a BSBA and getting a BS with a 2nd major in Olin?

I know that BSBA students have to take a lot more required classes in Olin than 2nd majors do, but what about after graduation? Does it matter to employers or anything if I receive a BSBA degree vs just getting a BS degree with a 2nd major in business if I want to go into business?
Also for study abroad, it says that 2nd majors are decided on a case by cases decision, so is it harder for ArtSci students with a 2nd major in Olin to study abroad at a Olin program?

Im in ArtSci right now, and Im pretty sure I want to go into Business after graduation… I’m just not sure if I want to transfer to Olin
