Two drawers that are different sizes is perfection! If you have a small load, like we do most of the time with just two people, you can use the small drawer and it is very convenient. Larger, or dirtier, loads can be done in the larger drawer. I do like that you can run both drawers independently of each other and at the same time. The drawer and rack design is great as it allows flexibility in how you load, and the side movable shelves are genius and very handy. Given that there is only a bottom washer arm, you do have to load with that in mind, but it hasn't been an issue so far.  
The drawer fronts are a nice addition to our kitchen, and the low sound level is also a great benefit. I like the knock to open feature if you need to open the drawer mid-cycle.
