Either way works, but personally I think a long break between POV's gets a bit difficult to read and it can seem jarring coming back to someone after a while away from their perspective. A shorted period of time keeps each character fresh in the reader's mind. I'm currently reading a series of books which has approx. 10 characters who's POV's it swaps between but it's little jumps, usually within chapters, and even though there's so many it really does work.
