No. While we like some models better than others, all of Amazon’s Echo devices are very high quality. The later generations of speakers produce better sound than the older ones, but if you’re primarily using a smart speaker to control your lights or ask for information, versus playing music, sound quality isn’t all that important anyway. Amazon’s Echo Show smart displays are differentiated primarily by screen size, so the bigger the display, the higher the price tag—with one exception: The sale price of the Echo Show 10 (10-inch display) is the same as the Echo Show 15 (15-inch display). The difference between those two models is that the Echo Show 10 is equipped with a motor that spins its display so that it’s always facing you. The Echo Show 15, meanwhile, is designed for wall mounting, unless you buy an accessory.
