As a home mechanic and bodger of some repute, I have mainly bought Makita in the past Andy, but do have some De Walt stuff. The De Walt DCF990 has such good reviews it was a no-brainer especially for the LR.
It is a mans tool weight wise, but like any good battery power tool it is perfectly balanced, easy to control and seems superbly designed and manufactured. With the three speeds/torque there's a setting for any job. Low speed did the wheel nut on the missus sports car and mid speed some scaffolding bolts that had been up at the back of the garden for two years. I'll be doing the front axle pinion seal on the LR soon, so I guess the pinion nut will not be so much of a problem as it has in the past plus a new hub is called for on the rear so we'll see how a new 52mm impact socket does it job.
I have noticed that whilst charging the 5 amp batteries that the charger runs quite warm as unlike the Makita chargers the smaller De Walt item is not fitted with a fan. My preference would have been for a fan assisted charger. It's not difficult and reasonably cheap to fit a fan to a charger so not quite sure why De Walt does not have one. Certainly I will retrospectively fit one after the warentee (3 years) runs out.
