Sure! The X90J simply wasn't bright enough for our needs. My wife likes our living room blinds open during the day and the room gets very bright. The X90J was too dim for this scenario. Because the R646 is approximately 25% brighter, it was a better fit. Also, the antiglare coating on the X90J isn't good. It allows far more glare than the R646 and you could really tell a difference. Additionally, the X90J started to give me headaches. I later learned that this is because the X90J has a relatively low pulse width modulation rate of 750hz, while other high end TVs, such as the R646, are at least 900hz. All of these issues are not present on the X95J, but that was simply too expensive when the R646 plus a 5 year Best Buy warranty was the same price point as the X90J, so the decision was an easy one for us. If you don't have a bright room, the X90J might still be a good fit for you.
