The Mueller 4 Slice and the Hamilton Beach 31127D 6 Slice are both conventional, analog toaster ovens. Considering their difference in size, it’s quite impressive that the Mueller only loses out in its overall score to the Hamilton ever so slightly.

In terms of design score, the two toaster ovens are quite equal. The Mueller has a detachable crumb tray for cleaning the interior while the Hamilton has a roll-top door that moves out of the way to bring food in and out of the oven more easily.

Both units only have analog control dials and no internal lighting so there was nothing particularly convenient about them. The Hamilton does offer more cooking space though, fitting 6 slices of toast despite being a medium size.

Their performance scores, however, was an interesting upset, with the Mueller actually winning. The Mueller was better at toasting bread, baking pizza, and roasting whole chicken in spite of its lower power draw. It only lost to the Hamilton in baking fries.
