Conclusion:

Cordless Drills mentioned above are one of the most Ranked Cordless Drills. Cordless Drill's Selection requires many parameters like Torque, Speed, Battery capacity, Price & Drilling capacity. 

Clearly, for a person with no price issues, go for Dewalt Cordless Drill as it provides best Torque and highest RPMs. Its only drawback is its price as it is most expensive in the list.

While Black+Decker, Dekopro & Avidpower provide cost effective cordless drills & if we discuss them one by one, we see that dekopro drill is most cost effective with more RPMs then Black+Decker & Avidpower but delivers very less Torque. On the other Hand, Avidpower & Black+Decker compete well, both provide better RPMs & Torque, & Clearly Black+Decker has more RPMs & Torque. 

Among all, Dewalt is the most Preferable one, and apart from Dewalt it is a bit tough to say which one is better as the three remaining brands compete well. But overall, it is Avidpower which has most balanced features then dekopro & Black+Decker.
