I have a 7+ 128GB. Previously I had a 6+ which ran great and had no issues. In comparing the 6+ to the 7+ I have found the 7+ to be faster. I have had no problems with the hesitation or jerkiness. If anything it will move too fast and I open stuff I didn't intend to open.
I have tried opening lots of apps including mail and safari - it is totally smooth. I really love my 7+. The improvement in the camera alone was the selling point for me. I have shot some awesome video with it.
So I wonder if it could be the batch of iPhones your carrier is getting? I don't know but if you are that unhappy take it back. The thing is too expensive to be unhappy with it.
