Who has the best cell coverage?

That is pretty cool. I wish we had something like that by me.

 

I wonder how their maps compare to the Mayor's unscientific 'study'.

The only problem I see with this is they are showing "Signal Strength" and not actual calling abilities with each carrier.
It is an excellent idea to have comparison's for consumers to make a good choice, but as we all know signal strength alone doesn't always mean a call can be made/recieved or held, and I think this can be useful for stores to have with a little bit more information.
