Bought an 18 v Milwakee set when I started my build, but that was 10 yrs ago. Things change, opinions differ, but here's my experience.
1st, that kit was huge to have on the build. Never realized how valuable a cordless circ saw and sawzall would be. For quick jobs, I still pull out that cordless circ saw. It rolled off the roof, 13' high, and bounced off the rocks twice. Still works great. Drill was put to the test driving many larger and longer screws ( hybrid timber frame). Brother in law beat the **** out of the drill in hammer mode one day drilling into basement concrete when I wasn't looking. It does the job, but when you have a lot, a real corded hammer drill makes sense. My helper pulled out his shiny new 'yellow' kit during build, and back then, the Milwaukee easily outlasted him on batteries. You can see his sadness when his quit and i was still driving screws hard. I have rebuilt or replaced batteries, but still use everything today. Got a free Makita cordless impact driver back then, and I must admit, it's a nice tool, good batteries and still works great. But, the Milwaukees took all the beating.
