Brett ... I know how hard the decision process is ... I just went back and forth for weeks comparing the Mits 73" and the Samsung HLS7178. What I did was read every thread here covering these tvs, and then looked at them in person. Even then, I was torn, but came down on the side of the Samsung ... for some reason, I liked it better ... but I imagine I would have been happy with either.
It's probably the same with you ... if these tv's have the features you're looking for, then pick the one that you like best (or that you can get a good deal on) and give it a whirl.
I imagine they'll all be fine .. and all should give great PQ with the PS3 (I'm assuming they all have HDMI inputs, as I didn't research the Toshiba and JVC). Good Luck with your decision.
