It depends. If you would like to make it clear that you use the same value again and again, I'd assign it to a temp variable. I'd do so if the call of the getter is somewhat lengthy, like myCustomObject.getASpecificValue().

You will get much fewer errors in your code if it is readable. So this is the main point.
