Yes. I do believe brand does matter, on some things more than others, and not always the most expensive it best, but there are some brands that are better, pure and simple.

I wish it was as easy as choosing one company for all supplements but it isn't. I use many brands.

I don't use natures best for anything but I do use Dr's Best for a few things and I like it, however not for everything. I use to use Dr's Best benfotiamine but switched to another more expensive but for me better brand.
