Public vs Private Audit Job

I need some help making my decision for the roles I apply for when I leave my Economics MSc. Which would you recommend, private or public audit?

I am of course going to apply to both, but I want a focus in my applications and so really am unsure as to which will suit me best. In particular, I need an insight into their culture differences, salary, and if they vary in how interesting they are found, generally. 

Thank you in advance for your help!
