Comparing Xfinity vs. Verizon Wi-Fi, Xfinity is your winner. Xfinity has over 15 million hotspots nationwide compared to Verizon’s 5,700+. With Comcast, more hotspots means less data drained and more connectivity and support throughout the country. Verizon won’t charge you for your data use, but you may prefer having more easy-access points if you travel frequently.
