>From your own experience, what do you end up using more?
Between those two, I use the drill more.
I don't have an impact wrench. I just use a rachet and socket set or box end wrenches when I have to wrench on something.
I have put hex bits on an impact driver when I had to drive hex head lag bolts into wood.
An impact driver is a good tool, and probably gets used more than my drill.
But if I had to only buy one I'd buy a drill first.
Then an impact driver.
Then an impact wrench if I needed to work on my cars (but like I said I do fine with wrenches and ratchets).
