Deloitte Financial Advisory M&A vs Investment Banking M&A

Hello everyone! I was wondering if anyone of you has an idea of the work-life balance in Deloitte Financial Advisory M&A (within corporate finance, not transaction support) compared to WLB in Investment Banking M&A.

I'm asking because I guess the salary in Deloitte is much lower than IB so I would not want to work the same crazy IB hours while being paid much less.

For context, I'm not referring to US but Southern Europe.

Thanks to those who can help ;)
