MBB > IB for PE exits? (Europe)

This is a genuine question...

I am aware that traditionally, this is not the case and that some MFs out there only take bankers.

But let's be real: people greatly overestimate the number of seats at MFs and their chances of landing one. But if we look beyond that (at UMM/MM), I feel that there is hardly any placement difference in Europe between IB and MBB once you account for the selection bias.

And it would make sense: Active value creation through operational improvements becomes increasingly important as assets are priced at record multiples and secondary BOs are on the rise. There's no free lunch left, no exploitation of mispricings or simple P2Ps of badly run conglomerates. Instead, PEs will have to work to make up the premium they pay, invest in hairy situations, and push for actual operational improvements.

Wouldn't this put MBB > IB for PE exits?
