Sprint is slower than AT&T because Sprint uses CDMA, which is always going to be slower than GSM/HSPA+ that AT&T uses

If you use your a lot of data Sprint is the way to go! Call customer care and have them go through the settings if your having issues like that.
It all depends on your coverage where you live. I was on sprint with no issues for 2 years. Their speeds are very usable when you factor in that they are unlimited. I had to switch to AT&T when sprint had several towers go down for over 6 months and refused to repair them. Up until that point I was fine with them. It all depends on the service coverage where YOU are.
