@M Miller, having a large sink with off-center drain allows you to place your trash pull out under the sink. You can then place a DW on each side or a DW on one and a drawer stack on the other side, so you are using the space under the sink that is usually wasted with some cleaning products, that you will still have room for, on the other side of the sink. I could have done it on mine, but have enough storage that claiming the wasted space under the sink was not important. I also like a deeper sink (10") and I believe to get the trash under you have to go with 8" deep sink.
Some examples:
