I bought ONIDA SPLIT AIRCONDITIONER a month back. it is a five star rated a/c. I dont know the price comparision but IT MAKES HELL LOT OF NOISE.
Window a/c is better than the split. Samsung is a sleeping puppy when compared to ONIDA. folks please think twice before investing on this  piece of junk which will ruin your peace of mind by  great noise. AND about the five star rating, god knows. I need to check on the power bill. good luck
