Expired domains traffic VS popunders

hi
i was wondering if anyone has any experieance with expired domains traffic
vs other types of traffic such as popunders / full page popunders etc
my logic tells me that traffic from expired domains should be more targeted since the surfer is searching for a similar type of site as your own and is simply being redirected to your site but i was hoping that someone here might be able to give me a better answer

thanks
