I am about to take the plunge for a higher end 46-47 inch LCD to change my 2 year old Pioneer 4270XA plasma. Trouble is I will be watching 70% sd via the built-in DVB-C tuner and I know that large diagonal full HD LCDs are generally not very kind to SD. I've narrowed it down mainly to these two based on reading some reviews and this forum. I would appreciate all advice and especially if someone has seen both in action...
