I'm currently looking to buy either the Philips 26PF8946, the Sharp LC26GA5 or the Hitachi 28LD5200. I'm trying to compare response times, and the Philips and the Sharp both quote 16ms, whereas Hitachi say: "The response time for the 28LD5200 is 26ms, however with the special overdrive circuit inside the unit the response time is lessened to 13ms." Does this mean that the Hitachi has a faster or slower response time than the others? Any other helpful comments welcome. Thanks.
