Experiences with Sprint??

I'm sick of Verizon, and ready to move on. I have just recently graduated and am looking for something cheap but I absolutely need unlimited data. Sprint seems to be the obvious choice here for 80$ a month I get unlimited everything, and yes I know T-Mobile is 70 but then I have to pay monthly for a phone. Amazon is currently offering the HTC One for $29.99 with a new 2 year contract on Sprint so that's my current choice.

My question really is, what are your experiences with Sprint. I'm sure customer service probably sucks like most carriers, but I want to know if I will be noticing a huge difference in terms of signal strength and data quality coming from Verizon? Will I have to worry about being in a city and not being able to find signal? What are your experiences day to day with Sprint? Thanks
