I don't think there's a time I can remember when Norm Abram (probably now one of the greatest or at least most prominent carpenters of a generation) ever mentioned the particular tool brands he was using.
And looking back on earlier seasons of This Old House, he was hand-nailing thousands of nails a day (nowadays he and everyone else often uses pneumatic tools for this).
I'm sure he prefers a certain brand, but unlike popular YouTube personalities and more 'celebrity' builders, he isn't a brand ambassador for Craftsman, DeWalt, Milwaukee, Ryobi, etc.
But yeah, when you talk about 'builders' (the more common carpenters you encounter on most job sites), it seems like most of them will die on a sword defending whatever brand(s) they've sunk a fortune into.
I'm a DeWalt guy, mostly because I invested in a 20V Max drill a long time ago and have a ton of batteries for all my electric tools now. But I used to use Makita before switching systems. I wouldn't call myself a master carpenter by any means, but like AvE, I find good and bad in almost all the 'top tier' lines from tool manufacturers.
You want it written in C for a 16bit bargain basement ALU? I can do that. You want two implementations, one in Pascal and the other in PHP? Not a problem. You want my advice? No? That's fine too, the advice is expensive and who knows after all these years if it's even worth anything.
At my first job we used to build some hydraulic models in hard wood that where works of art.
Our wood shop was so good they made a museum quality piece of furniture for our retiring boss and it was better than the best Chippendale furniture when new.
I do like the grips and ergonomics of some brands more than others.
The one piece of concrete advice I got was “Whatever brand you get, go for the 20V, not the 12V”. Last week I saw that same guy at work showing off his 12V driver. So I’m pretty sure nothing matters, and I’ll probably just get the brand with the prettiest color.
