Best for Impact
Been trying for a while to find the best bits for my impact driver. I've tried quite a few different brands, and recently decided to go for the Wera Impaktor set, which cost a fair bit. The performance and life were better than there without doubt, but they don't last forever, and the price of these is much much better.
I find that eventually these either break of they grind down too much, but with a box of 25, I just chuck them and forget. The Wera bits last longer, but with these I tend to have longer with a sharper bit before I can afford to bin it for a new one. With heavy use, I'd expect to get 2 days out of one bit (about 500 - 1000 screws).
I've also spent time tracking down my expensive bits on site before, if somebody nicks one of these, I really don't care. The disposable price point of them is the winning feature for me.

Dewalt 25mm Impact screwdriver
Generally I find that the Dewalt bits PZ#2 x 25. They are ideal for the majority of jobs I do on a DIY basis.
Good price at Screwfix.
The impact driver bits come in a black packet where as the ordinary screwdriver bits are in a Yellow packet.
