Google Fi is now just T-Mobile service given that Sprint and T-Mobile have merged.

T-Mobile's network has gotten quite good, but there will be areas where Verizon or AT&T are better (and there are areas where T-Mobile is better). T-Mobile is still integrating the Sprint network, but when they're done in around 12-18 months they'll have significantly more towers than competitors. They likely will still be working on expanding into some more rural areas, but within their footprint they should be very strong. T-Mobile will also have more spectrum which means more reliable service since there's more capacity.

Google Fi is upfront about data throttling. At 22GB, you'll drop down to 256kbps. The plan is really a 22GB plan that doesn't have overage charges.
