TV comparaisons

[Rike255]

I'm looking to buy a new 46" LCD TV and I'm wondering what the members here think is the best one to buy:

Samsung LNT4671F http://www.samsung.ca/myhdtv/
Sharp LC-46D92U http://www.sharpusa.com/products/Mod...8,1822,00.html
Sony KDL-46XBR4 or Sony KDL-46XBR5 http://www.sonystyle.com/webapp/wcs/...0151&langId=-1

What is the difference between the Sony KDL-XBR4 and KDL-XBR5 anyways? I couldn't see anything different except the price. EDIT: Nevermind I found a thread on it. Thanks though.

If you think those are bad ideas and want to suggest something else, I'm looking for a 46" or larger LCD Full HDTV with 120Hz refresh rate. I just went to Leons today and saw the difference between 60Hz and 120Hz on the new Samsung models myself and it is AMAZING so 120Hz is a must.

Other then that I wasn't able to compare the Sharp with the Samsung or Sony because nobody had the Sony on display and the Sharp was on the other end of the store so comparaison was hard to do.

What do you think is the best to buy?
