PhD or MD for Life Sci MBB/ER/IB?

Pretty much the title! I'm currently a student with a strong basis in drug development and biochem research. I'm very interested in the bench to bedside process, and although a majority of my experience is on the 'bench' side, I do want to focus more on the business and financial aspect of getting drugs to market.

I figured Life Sciences IB MBB consulting, or ER would be a great jump-off point, but I want to get a grad degree first. I'm planning to finish undergrad, do an MD or PhD, an MBA, THEN join Wall Street

Question is, for my goals and aims, is the MD or PhD more valuable? Which one do firms want to see more? Which one is more impressive to big pharma clients in the future? Should I just do something other than IB, Consulting, or ER?

Thanks!
