I was comparing a 32 inchTosh PF2 and Panny PD30 today (they were side by side).
Both had the usual dodgy geometry.
The tosh had great colour reproduction and a very natural picture (not much evidence of over processing).
The PD30 had a more dynamic and sharper picture with more depth. However, on this set I noticed more processing evidence which could prove annoying.
I had them set up with similar contrast, colour etc.
I guess it depends on what you prefer.
