Panasonic G30 vs ST30

[singhcr]

According to my research, I've found the following differences between the ST, GT, and VT series.

ST = Full HD 3D, Infinite Black 2 panel
GT = ST + THX certification, 48Hz mode for 2D
VT = GT + ISFccc controls, 96Hz mode for 2D and new Infinite Black Pro 2 panel for the best blacks of the three

So despite the fact that the ST is cheaper than the GT, you would say it has a better picture? I am looking for the best color reproduction, particularily the black levels. That to me is the most important thing in a TV. Is it correct that the GT beats the ST in black levels, but the VT beats the GT?

I have read that the GT and ST share the same panel so the only difference between the two is the bezel and the GT's THX certification. I could care less about that as I will be using custom settings anyway.
