That was the case in the past, but T-Mobile were actively building up their network in the recent times so it should be a lot better than before. I didn't compare it myself, so can't say how much it has improved in areas where it was bad before.
I switched from Verizon to T-Mobile a couple years ago, and where I live (Oregon), T-Mobile's service is absolute garbage compared to Verizon's. It was fine in the dense parts of the city, but anything outside of that was a total gamble. Driving to the mountain, the beach, or really anywhere outside the metro area nearly guaranteed a lack of service all or most of the way. I even had poor reception in parts of my house, and would sometimes lose calls in my kitchen!
I recently switched to AT&T and am much happier, but there are still occasions where my wife (on Verizon) has service but I don't. I've also heard similar anecdotes from people I've met in other parts of the country, so I don't think Oregon is the only state for which this is true.
(Before you say that this was a problem with my phone, I changed phones once while I was still on T-Mobile, and the service did not improve.)

It's all regional. There are places in America where T-Mobile is streets ahead of Verizon.
The upper Midwest, and the Gulf Coast, for example, because T-Mobile bought VoiceStream, and PrimeCo, which were dominant in those areas years ago.
Between personal and work devices, I carry AT&T, Verizon, and T-Mobile with me almost everywhere I go across America (usually two or three different states a month). Verizon is best in populated areas. T-Mobile is best in lower density places. AT&T is something of a crapshoot. Some places it's incredibly good, and some places it's like trying to make a phone call on an angry hedgehog.
> There are places in America where T-Mobile is streets ahead of Verizon.
Nonsense, it's not even a comparison. Tmobile is complete garbage coverage compared to Verizon or AT&T. I don't believe there is any place in the US where Tmobile has better coverage than Verizon.
Yep, exactly. So if you happen to live somewhere that's only well covered by Verizon, and consistently good reception is important to you, you don't really have a lot of other options. It's similar to the situation with ISPs in the US.
