LinkNYC is still rolling out, but, in my experience so far in Manhattan has been pretty great. They have strong backhaul, good radios in the devices themselves, and enough of them to make a mostly-continuous network on heavily traveled avenues. https://www.link.nyc/ https://www.link.nyc/ TransitWireless, the in-subway wifi in many train stations here, is comparatively much worse - but tbey also provide underground cellular service, which is almost always usable.
