First off, welcome to your forum! Secondly....if you are buying one tool....I'd go with a drill. The reasoning is that the drill is going to drive screws, it will also drill holes. The impact driver can drill holes too but...it is really and ideally used to drive fasteners. The impact mechanism allows you to use the high torque and impacts to really pound in large fasteners. One could argue either way but the impact gun is a phenomenal tool all around but the drill is my go to tool. If you think about what you are going to be using the tool for mostly then it is easier to make that purchase. Keep in mind, when you purchase either Dewalt, Bosch, Makita, Milwaukee you are really buying in to a tool platform powered by one battery platform. That first purchase can quickly lead to a cordless circular saw, jigsaw, recip saw, impact gun, right angle drill, lights, radios, sweet Lord Above the trail never ends. However, for my two cents, I'd get a drill. It's going to do light duty fastening, medium duty drilling and make life happy. The get your impact. Then the smiling starts. Also, don't think that an impact gun is going to take lug nuts off of tires, you need an impact wrench in most cases for that. Good luck dude!
