What is the actual difference between BB vs EB vs MM?

These distinctions just seem super arbitrary and I don't really understand the difference.

Looking at the league tables, Evercore and Barclays have about the same numbers for M&A. Why is Barclays a BB and Evercore considered an EB? Evercore also has equity research/S&T departments, so it's not like they are only advisory (which I've heard people say before is the distinction). Evercore also does various different types of advisory (RX, M&A, ECM, etc) so they seem like they are on the same level as a BB.

Next, what's the difference between a slightly less prestigious EB (ie Rothschild or Jefferies) and a top MM (ie Blair or HL). They are doing similar deals (many of the 'lower' EBs are moving more downstream into 'middle market' deals) and are not too far away on the league tables. Blair also has a PWM, equity research, etc division and a bunch of global offices, so I don't understand why they are considered that different from somewhere like Jefferies.

Can anyone explain this rationale to me? Thanks!

You couldn't find the answer to this anywhere on the internet??

I just Googled literally the phrase "difference between bb eb mm" and found this excellent and accurate article from M&I. Do you have specific questions beyond this?

EDIT: Read the article, morons giving MS. Ranking banks is stupid, and the BB/EB/almost BB/MM distinction is mostly talked about by undergraduate students. You'll never hear the fucking term "Elite Boutique" outside of this forum or the analyst bullpen.

Be excellent to each other, and party on, dudes.
 

yes because they're all the exact same structurally and there's literally no difference in size, headcount, prominence, exits, resources, lending capabilities, clientele or anything at all between any of these EB/BB/MM/BSB/Small Boutique firms whatsoever.

100% man, basically the entire industry is one firm - right?
