Eggo blueberry waffles
You can find Eggo at just about any store in a variety of boxes and flavors. You can even pick them up in bulk or family sized packs. While they were pretty good, these waffles didn't cook as quickly in the toaster as some of the others that I tried; they also needed a higher setting than most of the foods I cook in the appliance. If this is all that you make, you can put it on the right setting and leave it there, but for me, it would require constantly adjusting. I rely on frozen waffles for a convenient breakfast that requires minimal thought, so even that small thing moved these further down on the list.
Eggo is also one of the more expensive options out there at around $4.50 for a box of 10. Given that the taste isn't any better and they require extra adjusting, I just can't justify spending more on Eggo.
The thing I liked about the Eggo waffles were the generous amount of blueberries in each one. The squares were also a bit deeper than some others, which helps them keep the syrup in place. I probably wouldn't have noticed this if it weren't for the side-by-side comparison, however, so don't expect anything really drastic. I went with the standard blueberry waffle for this test to keep things fair, but I've tried the thick and fluffy version as well; they really are quite a bit thicker and ideal for holding extra syrup.
