Is iphone 5s better on Verizon network or T-Mobile???

I just bought an Iphone 5s on the verizon network because I was told its the best network. But I saw that T-Mobile has the iphone 5s for 0 down on their network. I know they charge you $27 a month for the phone along with $50 a month for the data plan. So its roughly $80 a month for iphone 5s with unlimited talk, text and data versus the verizon plan with one of their lowest data plans is about $90 a month. Is T-Mobile's network decent enough that i could really enjoy all the phone has or is it better to just suck it up and pay more for data with Verizon???
