Engineering...especially in the energy industry will get you a lot further in the long run than a masters in accounting. Big oil outside of their finance areas look very favorably one folks with engineering degrees, its a near requirement for Exxon, every person at Kellogg with an offer for their GM program this year had an engineering degree. If you want to be on the finance side I think accounting will help but strategy, business development, operations, etc all will prefer engineering. Consulting I think it depends on the company and what you want to practice...I know the MMM folks at Kellogg do very well with the top consulting, and most of them have engineering degrees so it stands to reason that it will help. I think far fewer folks have advanced accounting degrees.
So IMO corporate finance, banking, and things like that will prefer accounting. Pretty much everything else the engineering degree will probably be more leveragable.
