re: Best brand tool ecosystem to go with?

I figured I'd wear a set out on the barn build and was going to buy a kit anyway, and since the metabo 30° nailer was on special when I bought, I went with them. I dropped an 18v impact driver from the scissor lift and although it still works, the flipper forward/rev broke. I caught the 36 volt triple impact on sale with two batteries and it's a beast. I bought the tin nibbler which has been terrific for coping the exterior PBR Panels. The 36 volt 7 1/4 circular saw is also a workhorse. I've marked the blade offsets on each side for using a cutting guide. My dewalt tools are holding up good, just don't seem to get the battery/tool specials that I can justify. I bought the metabo 10" 36 volt miter saw but really wish I hadn't. My old 12" Porter Cable with laser that is dead nutz is still going strong.
