Make sure you always have a controller charged and ready by picking up a spare. GameStop have them back on offer again, saving you at £3-15 over the other sites. I've been loving the new controller since getting a PS4, the new triggers are fantastic and the analogue stick grips are vastly improved. My only concern is the ongoing deterioration of the rubber on the analogue sticks. Battery life is reasonable, but plugging headphones into the controller or playing games that use the built-in speaker can drain it pretty quick. Charging times seems quicker than the DS3 though. Note: you don't get an extra micro USB charging cable with extra controllers.
