Which one of these tvs would do the trick?

II have done my research and I've come down to these three: LG 42CS560 42",Samsung 40" UN40EH5000,and Panasonic VIERA TC-L42E50. which would you Recommend for Gaming specifically ps3 gaming, with input lag into consideration and such. I heard the panasonic tv has the ips panel in it, which means it has less input lag. Thanks again for any information provided!
