We used to. Wife used to be with Verizon then I was with att. She had Verizon through work concessions and it was much cheaper for a while. She even used to get a new phone free (to her) every year (iPhone was excluded but she could sell it or otherwise do what she wished). That changed and eventually a family plan was the better deal so we both moved to ATT. We are now on T-Mobile for the same basic reasons you are. She has complained about a dropped call here and there on her drive home from work, but we are saving about $80 a month (part of that is that buying/leasing devices is cheaper through promos), we have more data, and of course streaming videos. My son used 18gb this last month in YouTube steaming. I used 16 between Netflix and music. For us, right now, T-Mobile is the answer. The way I see it, for almost $1000 a year, I'd have to have much greater problems than an occasional dropped call. Of course, I do see 4g much more often than I did with att where I only really saw LTE anywhere I went, but aside from that, I'd hardly notice.
We will be going on a cross country road trip this July l, so that should be interesting. MA to CA. We will see how the connectivity is in the road as we are sure to be streaming for most of it should the connection be stable.
