Healthcare Consulting Firms: Huron, Navigant, or ZS?

Did some browsing but couldn't find any recent thread regarding healthcare consulting firms and specifically these three firms. Currently have offers from Huron Healthcare (general) and Navigant Healthcare (Revenue Cycle Management) with a final round interview scheduled with ZS later this week. The Huron offer explodes this Friday.

Could anyone give me a rundown of the strengths/weaknesses of each firm? To provide more light into helping make a decision, Navigant has the better comp package, and I personally liked the culture/people much more so than Huron. Although I would be working within RCM, there is the opportunity to work on other projects across different segments within healthcare. Huron is ranked slightly better, but I am curious to see where/how. As with ZS, obviously pharma sales & marketing focused, but what would be typical exit opportunities be afterward? Would I be limiting myself to life sciences work or sales and marketing?

Thanks for all of your help. I can provide more information as needed.
