PwC TS Valuations or Financial Data Vendor?

Hi:

I am currently with a financial data vendor (think Bloomberg, Reuters) doing portfolio valuations work (working with middle office of mid-sized banks and Fund managers, HF, insurance companies to deliver their end of day valuation results , etc).

If taking the PwC TS Valuations position, how much more/less career growth should I expect? My current group at the data vendor is a bit stressful during certain times of the day (no busy season, just daily crunch time of couple hours)- is this likely to worsen or improve?

Part of me that's leaning towards PwC is that I could have more opportunities to work on building up business cases and network with clients in fields i may find interesting in the long run, such as M&A and IB(?). Would this be enough incentive to make the switch?

Any opinion is appreciated!
