Canon 77D

One of the local big box stores is having a sale on the Canon 77D. Does anyone know how this compares to the 70D or the 80D?

From dpreview:

So is the EOS 77D more than a fancy Rebel in disguise? Well, not really. The only meaningful differentiators between this model and the Rebel T7i it was announced alongside are the dual control dials, top plate LCD and the addition of an AF ON button. Less meaningful differentiators include an extra eight grams of heft and some general button shuffling. And that's it.
