Yes I think it's more convincing to counter-offer after a break because it conveys that you took some time to research your options and aren't just providing a knee-jerk reaction to their offer. Of course, don't counter-offer unless you're prepared to walk away if they fail to meet it. It's a high-stakes game, and sometimes you'll lose. The amount of time you ask for should fall in line with whatever narrative you've been weaving. If you've given them the impression that you're a sought after candidate with many suitors then asking for a few weeks to wrap up your other interviews would not be out of line. But it's very case-specific, you've got to keep in mind how much pressure they are under to fill that position fast. I typically say I'll get back to them next week.
