Age, experience (instrument rated, use to complex types, flown a variety of types etc), aptitude, maturity, they are all factors.
A great deal can be made of whether you fly a circuit as precisely when you are current, as after a 60 day break. It is no different from flying competition aeros - the more current you are the better your performance will be. If you are flying circuits every week, after a 60 day break your circuits will not be quite as pretty. Who cares? However, that is not the criteria that should be applied to currency.
Are you likely to be able to safely compete the task you have set? Are you likely to be able to handle any emergency that might occur at least very nearly as well as if you were a bit more current? Give yourself a PFL - it is a pretty good test of how much rust has accumulated.
However, I believe the two key factors are those a gave earlier that most effect the average pilots ability to take a break from flying.
