I see a lot of guys using 1/4" drill style impact drivers. Bosch is one of the ones I see a lot of.
I have a Hilti one that is a lot more expensive, but very nice. You have to be careful not to over torque the fastener and shear it off.
The ratchet can get into tighter places, but I have always found a way to avoid that. The drill style has many other uses, so is my preference.
