Gee wiz that’s tough to answer. It’s hard to advise someone on a tool purchase without knowing more specifics. You say DIY use, so I will presume you won’t be drilling 2 1/2” holes through 2 X4’s for pvc or 5” holes for recessed lighting. I love my Milwaukee 12V max platform and use it for at least 80% of my work, however, if I had to choose to use only one of the two drills you listed I have to go with 18V Makita. Likely it will accomplish anything you would want to throw at it.
