My son works for Best Buy
Anyway,I bought the stainless steel LG dishwasher because they have a very good reputation. Unfortunately, when the installer came to my home to install it, he couldn't get it in with my wood floors. I had to exchange it for another dishwasher. He recommended Kitchenaid, which is owned by Whirlpool.
I don't think you can go wrong with either brand. I liked some of the features on the LG.
Make sure you measure the height from floor to your countertop! The LG style I picked did not have an adjustable height like the Kitchenaid I exchanged it for.
