Early-on, I found that Nutricology / Allergy Research Group and TwinLab didn't work for me and/or were contaminated with crap. I won't take them, ever. I also try to stay away from Blue Bonnet (see below).
My favorite brand is Thorne, with Jarrow and Biotivia close seconds. The next tier is Carlson, Nordic Naturals, Life Extension, Now Foods, Doctor's Best, Natural Vitality and KAL. Third tier is Healthy Origins and MRM.
I also like a handful of other, physician-oriented brands, but I don't use them much: Douglas Labs, for example. I'm currently taking B-minus by Seeking Health, but I will probably switch back to B-Right by Jarrow (just need to double-check that it doesn't include "standard" Folic Acid).
In the course of my supplementation, I found some minerals corrected levels very quickly, and others were extremely slow. IIRC, it took like two years for my Molybdenum to correct, for example (taking Thorne the whole time). I also go through periods of being extremely sensitive to B vitamins.
Resveratrol is one that I noticed a huge difference from one brand to another. I started taking it mainly for blood sugar control, in 2009. I started with the best brand I could find at the time: TransMax 500mg by Biotivia. Measuring my blood glucose (BG) with a meter multiple times a day, every day, I could see a big difference. When my supplier ran out once, I tried another brand (TransMax isn't cheap, so it was also a hopeful change on that front): Blue Bonnet. Same strength, but it had almost no effect on my BG. I switched back to TransMax as soon as I could, and the BG effect returned. Haven't looked elsewhere ever since.
I had a big learning curve on Vit E, too. I took Unique E for years -- which is great. But I eventually learned about the differences between alpha and gamma tocopherol, and the importance of tocotrienols, and switched that around. Currently taking Gamma E by Jarrow, while rotating in tocotrienols a few times a year.
