Which samsung lcd is better?

I cant decide on a 52 inch.
LN-S5296D or the LN-T5265F.

I was gonna get a Sony Bravia 52 XBR3, but reviews say it doesnt even have PiP. Sharp doesnt have Pip either. Isnt that strange? Supposedly Samsungs use the same lcd screens as Sony, so I might as well save a few hundred.
What are your thoughts?

anyone have these lcds to help me understand the differences?
