"Nationwide 4G coverage" basically means if you are in a major city you will get 4G. Right now 4G is a joke, it isn't really "4G it's just faster 3G and more than likely you will not get it. Verizon has a decent 4G network, but when it comes down to it, you will most likely be on 3G and Verizon has the largest 3G network and the best talk network. T-Mobile is trying to do the same thing when AT&T said it's the "fastest 3G network" because it has .2MB/s speed than Verizon but about 20% the coverage. However, my Verizon is way faster than my friends AT&T, T-Mobile, or Sprint.
