Smart speakers have become the command center for modern homes, but choosing between Alexa, Google Assistant, and Siri creates decision paralysis. Based on analysis of expert reviews from Wirecutter, CNET, The Verge and other sources, expert consensus shows the marketing doesn't match reality.
The surprising finding? The "smartest" assistant often isn't the best choice for your specific home setup.
