Both drills are excellent products that will respond quite well to all domestic drilling needs. But the two products have a number of important differences, and one needs to consider them before deciding which to buy:
Power: The DeWalt DCD771C2 drill is clearly more powerful since it can reach speeds up to 1500 rpm while the maximum power it can deliver is 300 UWO. The maximum speed the Black&Decker LDX120C drill can reach is only 650rpm, and the maximum torque it can deliver is 115 in-lb which corresponds to a power level less than 300 UWO.
Batteries: Lithium-Ion batteries are better than NiCad batteries which are susceptible to suffer from what is called the "memory effect" whereby the batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged (the batteries appear to "remember" the smaller capacity). Both of these drills are equipped with Litium-Ion batteries which is great.
LED Work Light: For those who need to work in darker conditions, a built-in LED light that illuminates the drilling area can be very useful.
Clutch Settings: The clutch setting controls the amount of torque that the motor will transmit to the drill chuck. The DeWalt drill give you more settings than the Black&Decker (16 settings vs. 11).
Warranty: The Dewalt warranty is much better than Black&Decker's: 3-Year vs. 2-Year. In addition, DeWalt has a 90-day money back guarantee. All this simply means that DeWalt has high confidence in the quality of their products.
Given all the above points, our first choice is the DCD771C2. Note also that the DeWalt comes with a contractor's bag.
But if its higher price is an issue for you, at almost half the cost and with all the features it comes with, the Black&Decker LDX120C can also be safely considered.
