“Best” is doing a lot of work in that phrase
Any page or listing claiming to identify the “best” supplier is making a judgement call based on criteria that aren’t always stated. Before accepting the claim, it’s worth asking what criteria were actually used, price, documentation, shipping, or something else entirely.
Comparison content isn’t always neutral
Some comparison pages are written by, or affiliated with, one of the sellers being “compared,” which changes how much weight the ranking deserves. This isn’t unique to this market, but it’s worth keeping in mind here specifically.
What to verify regardless of the claim
Whatever a “best” list says, applying your own criteria, batch-specific COA availability, shipping practice, responsiveness, to whichever seller it points you toward is still worth doing before ordering.
Using rankings as a starting point, not a conclusion
A “best of” list can be a reasonable way to generate a shortlist of candidates to check further. Treating it as the final word, without doing your own verification, skips the part that actually matters.
The practical approach
Use comparison content to find candidates, then apply the same documentation and shipping checks to each one yourself, regardless of how confidently any single source ranked them.
