Execution Trader at BB or Trader at MM?

Hi all,

TLDR: Execution trader at BB or derivatives trader at MM (sell-side)? Career growth as an execution trader at sell-side/BB?

I'm currently working as a junior trader on a derivatives desk at a sell-side MM and have been fortunate enough to have ton of trading exposure (was given a book to manage as a first year). However, the downside is it still isn't a global IB after all hence the overall exposure you get (besides trading) is still limited I believe (the brand, global IB flow exposure etc., can only trade certain products).

Is it worth picking an execution trader role at BB over a trader role at a MM? In addition, what is the career growth like as an execution trader at sell-side/BB?

Thanks
