NL25 - 9 handed - a common situation with AA

[kosher]

I realise that hands like these often get posted but I'm constantly placed in similar situations to those below and always have trouble making a decision.

I suspect that good players make a decision here that is strongly based on villain's stats but what stats (if any) should I consider when deciding to push or fold here ??

Much appreciated.
