CAUTION: OPINIONS AHEAD. And, they mirror what many others say about a niche or strength.
As many have said, its hard to go wrong with most major brands - Milwaukee, Bosch, DeWalt, Makita, etc. Even value priced products from Hitachi, Ryobi, Rigid, Craftsman, etc. provide a decent tool for the DIY/Hobbiest (is that even a word?

).
Having said that, I think many companies have something they do very well; perhaps better than the others. A huge number of users/owners would argue a corded Milwaukee Super Sawzall is the benchmark for a reciprocating saw.
My Bosch Jigsaw has nearly 20 years and thousands of cuts on it; it still cuts smooth and true. Same for my Porter Cable Router, albeit with a lot less use over the years.
I am less convinced on circular saws. I own 2 DeWalts, a worm and a standard (both 7 1/4) and they work well. The Worm is a heavy pig but it's been called on to rip 3 layers of 23/32 on more than one occasion and done so with out flinching. I've used Makita, Milwaukee and Skill circular saws over the years and I have not found one to be dramatically better than the others. Just be sure to use a quality blade, no matter which flavor of saw you choose.
If I did not have Bosch Hammer drills, I'd have Hilti.
I don't currently own a corded regular drill, but I'd buy a Milwaukee if I needed one. I had one, it grew legs and left me years ago.

I replaced it with a cordless 18V DeWalt. It was not the same (meaning not a suitable replacement for the corded Milwaukee) and it did not last, granted it was the batteries that failed and this was 15 years ago when cordless tool battery technology was no where near where it is today. I have since jumped on the Bosch cordless bandwagon after buying and using a Freak...
I've been through Porter Cable (wore it out) and Bosch orbital sanders, neither impressed me enough to buy again or recommend.
I've never owned a Festool, Fein, Mafell, or any super premium for that matter. Talk about eXXXpensive

I'm sure they are great, but some of those are double the price of tier 1 (again with the Red, Yellow, Blue, Teal) options.
