I don't have a particularly large collection of power tools, most of it mid-grade stuff of several brands based on reviews of specific products (Dewalt, Makita, Rigid, etc), and a few more homeowner grade (mostly Ryobi) tools. Of those I have, my Bosch jig saw stands out as one that is noticeably better than any of the competing models I've handled - Much smoother, more stable, and with more of an overall sense of quality. Their blades are pretty good, too - reciprocating blades are sold under the Bosch name, but spinning blades kept the Freud name after they bought that company.
John Deere and Stihl get dismissed by some unfairly based on the fact that they both make regular homeowner grade products. However, they both also make professional quality equipment. You just generally buy those products at different stores, and you pay far more for them. That was always the case, though.
I've heard that Porter Cable still makes a quality handheld belt sander, but since Black and Decker bought them out, most of the rest of their tools fall right where their pricing would suggest: in between the Black and Decker and the Dewalt branded products.
FYI, there are two Rockwells that I don't think are affiliated. Delta's parent organization bought out Rockwell Power equipment about 35 years ago.
Are there any tools still sold under the original Rockwell lineage?
As far as I've been able to dig up, the Rockwell you now see at the Orange and Blue stores has no affiliation at all with the old company. It's a Chinese company that mostly made tools under contract for other brands. They simply bought the name from Delta around the time the Fein oscillating tool patent expired, and that seems to be their main product now.
I've got one of their Soniccrafter tools, and it feels pretty solid, although not very refined.
I don't think anybody has mentioned Jet for stationary power tools. I've always been under the impression they're pretty much comparable to Grizzly. I've only got limited experience with either, and in my line of work, they've always tended to be abused, so I couldn't give proper-feedback about either.
