Cordless-wise, I have B&D, Porter Cable, and Bostitch (drill and impact driver that they used to sell at Wal-Mart) because they are all electrically compatible SB&D products, requiring only a few kisses from a Dremel to interoperate like a single system. Also made an adapter for my ancient Ridgid X2 anchor, I mean DRILL; it was a gift and just sits on the shelf with a countersink in it, but it still works.
Got a little bit of everything for the woodshop, Wen jointer, Shopsmith planer, band saw, scroll saw, and Mark V, Sawstop Contractor saw, Harbor Freight Dust Collector.
I have a bunch of Snap-on tools that I rely on for various things. For things I don’t have, I go to harbor freight for a “good enough to at least get the current job done” tool.
I bought a bunch of Dewalt XR tools right after buying our house. I can’t compare them to anything, but so far they have been able to handle everything I throw at them.
My stuff is rigid, because I bought the hammer drill several years ago and it’s been outstanding so naturally when I need new tools I just get another rigid now.
