Hey welcome to the forums Imran! I personally have Dewalt but would always suggest Milwaukee if you need to greatly expand your tool line in the future, they seem the be the most innovative one out there atm. If you're just gonna stick with the basic drill/impact + maybe one more, you cant go wrong with any of them! Not sure on the availability across the pond. On the GSB 18 V-Li vs. GSB 18 V-EC issue, it looks like the EC is the brushless version. But the EC is rated at 17 nm less torque, in exchange for less vibration and longer runtime, So i can see you hesitation on which is better. I wonder if anyone on here owns both and can give you a better opinion on the matter. heres the links to both incase someone else knows better than I.
