PwC vs ZS

Hi all! I recently received two offers: Asscociate in PwC Advisory (Management Consulting) and Business Operations Associate in ZS. These are both not US based. My questions are the following:

Which one do you think is a better place to learn and start a career?
Do you think any of these serves better to get a strategy position in the close future?
Is any of these offers gonna narrow the spectrum of possible future jobs?
How prestigious do you think these firms are?
Which one do you think has better exit options?
Where do you think I stand a better chance to going offshore preferably EU/US?

Any other comment or suggestion is highly valued.

Thank you!

PS: I am already factoring things as "what job I would like more" or "what interests me" yet any comment is probably going to be useful
