Citi Corporate Banking vs BlackRock Client Analytics Group FT

Dear fellow monkeys,

I am a senior at a target school to graduate in May 2014, and have landed FT with Citi Corporate Banking and BlackRock Client Analytics Group. I am having a hard time deciding which one I should go for.

As much as I like both positions offering relatively good work-life balance (the latter seems to do a better job at this), I want to take into consideration exit opps I could have from them. I do understand the two are very different in terms of type of work I will perform as analyst, hence skillsets I will gain. Although I am not 100% sure whether I will want to make an exit to PE/HF whether via IBD or directly in the future, I definitely would like an accessibility to this option.

I'd appreciate it if you senior monkeys could shed some light upon my decision making given aforementioned conditions.

Thanks in advance!
