I just bought the 32gb Nexus 5 and will be switching from Verizon as soon as my phone arrives. Who do I go with, Sprint or T-Mobile? I know it is basically a $10 difference between the 2 unlimited plans but who has better 4G & faster speeds? I travel everywhere so I need plenty of coverage and speed. Am I really going to miss Verizon's fast speed and good coverage that much?
