To start us off I'll present a few examples from among the few brands that I really admire (until I have strong reason not to).

Leatherman Multitools, etc.

https://www.Leatherman.com

Not cheap, but brilliantly designed and made to last. I also like a lot of clever sporting and camping gear too, but that's less practical for daily use, and also expensive. I also like some power tool companies and their clever and/or solid tools, though IMO they're all overpriced.

Nag Champa incense

https://www.NagChampa.com

I don't like most incense, yet somehow like all of theirs. I don't know how ethical, sustainable, fair, etc they are. Feel free to school me on how it causes cancer or something.

Logitech

https://www.Logitech.com

I've been consistently happier with Logitech products over all other product lines I've tried over the decades with few exceptions. Would like them to be more recyclable.

Chronicle Books & Shambhala Books

https://www.ChronicleBooks.com
https://www.Shambhala.com

It's been almost 20 years since I had a "disposable income" to splurge, and before the Internet provided high quality images, books, and music I used to buy hard copies. Obviously I can't speak about all of the Chronicle books since then, or any other genres than the many art books I got, but they were (and are?) top notch.

At this point you might think I'm some kind of hippie. You're not wrong.

Umbra Design

https://www.Umbra.com

Also from back when I made good money, I used to like a lot of Umbra and similar unconventional higher end mod products, and though admittedly they had some mediocre stuff back then, since I've seen even more disappointing generic mass produced stuff out there with their name on it. It seems they couldn't resist selling out into something akin to Ikea. Take with a grain of salt that I haven't been a part of that world for a long time and the cutting edge styles from 20-25 years ago became popular 10 years ago and haven't evolved since IMO.

Frank's RedHot & Tabasco

https://www.FranksRedHot.com
https://www.Tabasco.com

We did a blind taste test in Austin and discovered I actually preferred Tabasco to Texapeppa. I'm guessing that Franks and Tabasco are owned by the 20 Big Food corporations that dominate most of our food supply.

Lego

https://www.Lego.com

I worry about anything plastic, but IMO Lego was great, though overpriced. IMO, with "advancements" the more "realistic" specific pieces limited the creativity of kids with their pre-designed kits that could only really make one or two models without room for imagination and options to build other things.

As a kid I also liked Mechano, but found it tedious to take everything apart after.

I literally just walked around my place looking for quality brands and that was all I could find.

I like many antiques and solid vintage products that seem brandless too.
