I have a dozen or so DeWalt tools that are great. My experience with Stanley is “OK”. I have zero experience with Arrow.
I personally would buy DeWalt. That’s just me.
I LOVE my DeWalt tools. All of them.
I suffered for years with old, nasty, corded power tools given to me or acquired from friends or family.
I convinced my wife to allow me to buy a suite of battery powered tools, and it has been utter joy for me for years now.
I am sure there are other manufacturers who make good tools, but my DeWalts are reliable and virtually indestructible, it seems. I have dropped them onto concrete from a ladder, and I have thought “No way is that going to function, but...it did...with only a cosmetic scuff where it hit the ground.
Love it. I regret all those years without them!
