brinda,
Whatever be the brand, the satisfaction of a clean wash is very much missing.
I use whirlpool sixth sense, my co-sis uses the higher end siemens but still both of us crib the same.

.
whirlpool service has been good for me. have taken a amc with them.
I have used LG when i was in muscat. did like it. but cannot compare both as the water is different.
water, soap also play a good role i suppose.
