Which is best amongst EY and KPMG for Internal Audit

I am currently evaluating offers from both KPMG and E&Y for internal audit. While I have my own marks for both of the firms, need your inputs on the following. You may also rate on a scale of 1-10 for the following aspects.

1. Work Life balance
2. Quality of work
3. Culture and how people are treated
4. Pay

Thank you.
