<p>My opinion</p>
<p>Ernst & young
Delloite
PWC</p>
<p>Not sure where kpmg would fall in</p>
<p>This is practically impossible to do, but here is a shot based on prestige, starting with the highest prestige. Disclaimer: I don’t think there is any way to do this with any kind of consistency, but I’ll just play along (and this is probably the best way to do it).</p>
<p>Deloitte</p>
<p>PwC</p>
<p>KPMG
EY</p>
<p>Deloitte and PwC are pretty much the most ‘prestigious’ but part of this is because of the consulting branches at each firm that booster its reputation, especially Deloitte. KPMG and EY are pretty similar.</p>
