I posted this in another thread, but about a week ago I was in an area with low signal strength. Normally I drive through the area going somewhere else, but I had car troubles (needed a tow and it took 2hrs to get a tow truck there). So I spent 2 hrs in that bad signal area. In the past if I was on a call before entering the area, a phone would drop the call somewhere in this area. In that 2hrs I spent there I made several calls and surfed the web for around maybe 1/2hr to 45mins. Never had any issues with either voice or data.
Now, like cbreze, I have the regular Pixel 2 and like you I'm on Verizon. The phones I am referring to aren't iPhones, but Motorola Android's from 2013 to 2015 and a Huawei Nexus 6p. Motorola phones are known for their stout cellular radios (they were the company that pioneered the cell phone) o they should be as good or better than an iPhone. While my last Pixel 1 was better than them, it would still sometimes have issues in that area. But my experience with the Pixel 2 was almost like I was at home with our LTE Network Extender covering the house. I didn't do a check to see what the signal strength actually was mind you, but it performed better than any phone I've previously used. Hope that helps.
