Barcap vs Commerz (previous drkw)...please advise!!!!!

  1. Trade support role (sitting with traders) at barcap - still consider as middle office role.
  2. Front office exposure managment at commerzbank - high flexibility to move to front office due to the extensive interaction and risk decision making process with the desks.

which one will give a better prospect to my career (incl. opportunity to move to front)?
right now both banks have put the same offer , but which role is likely to generate a higher bonus?

role by role, i am more inclined to the latter one. however, i am slightly worried having commerz on my cv does not look good either and given that the germany government hold part of the stakes this will hinder the growh of the organisation in a short run.

please advise! thanks.
