Which company?

Willis Towers Watson
Aon

#1

I have applied to a number of actuarial internships for pensions based schemes at:
PwC
Mercer
Towers Watson
Barnett Waddingham
Aon

I was just wondering what people thought would be the best company to accept an offer for if I was lucky enough to get more than one?
Any experiences of any of these companies would be really helpful!

Thanks very much!
