Don't underestimate the pioneers in Motorola and Nokia.
My Microsoft Lumia 640 sounded like I was talking on a landline. Crystal clear and I lived up in the mountains where 2G doesn't exist and only 3G. While my Motorola Moto E 4G had the best Wi-Fi range.
It's why I like classic Motorola and Nokia so much. They are the best for reception since they have been doing it the longest. Motorolas on Verizon (best coverage and strong signal in US) should be stellar.
Just keep in mind any devices or upcoming ones with band 71. V30 is the only one right now (I think) but next year they'll all have it I'd think. Even if band 71 isn't deployed in your area yet, it might be next year right? As for iPhone, it's the Intel modem. They cripple the Qualcomm one to make it inferior like the Intel. If they didn't, everyone would notice the difference right away. So until Apple fixes this issue with Qualcomm, I'm out.
