Thinking of buying a 46hx923

Hello everyone, I am thinking of buying a 46hx923. Is it better than this years 853/753 models. The price of the 923 has come down recently and it’s starting to make me think. I was thinking about getting the 853 but I am not sure that my room can accommodate the speaker stand as my TV is in the corner. I was thinking about getting the GT50 but my miss has no respect for technology and she would almost differently cause screen burn and IR as she has a habit of not switching the TV off properly which causes my amp to display a static image for hours on end or she will pause the TV on something and go about her business and you know that once it has happen of cause it would be “my thought” for buying a stupid TV which does that…..BLAH, BLAH, BLAH. The thing that is going through my mind is the crease issue and DSE. I have looked at a few display models and it showed the lines down the side of the set but not too badly but I guess it would be luck of the draw. I didn’t notice any DSE but didn’t have any material i.e. football panning shots to test it out. I also see that sony centres are no longer doing the five year warranty the and charging an additional £120 for it.
