It really really depends on which career path you wish to develop with your early career.

FS team can definitely help you to build a more favourable profile if you wish to quit big4 and work in-house for the financial service industry; while if you wish to continue to develop your professional service career (eg other Big4 or other consultancies with similar service offerings), seems choosing according to your feeling towards the firm that you experienced in the interview process will be better as you may devote a much longer time and career there in the firm...company culture / partner style is important as it may affect your satisfaction and performance which somehow affect your career progression within the firm as well.
