I wonder why you would switch out, other than a larger size. We have had Sharps for many years and have been quite satisfied. I know that Samsung is highly rated by Consumers Reports and that Sharp is not as highly rated, but the point differential is pretty small. Are they both LED LCDs or are you comparing apples to oranges. Is the Samsung coming from another RV or the house?
