This got away from me a bit. Skip to the bottom for the short version.
Honestly I only picked PureSci Labs because they were cheapest and had a working checkout, which in hindsight is not a great way to choose.
Trying to work out if what happened to me with PureSci Labs was a one-off or a pattern.
Support at PureSci Labs was actually pretty decent when I had a problem, which surprised me given what I’d read.
Worth noting there’s an Index Score of 89 for them published, which is more than I expected honestly.
Things I still don’t know: whether any of this is batch-specific, whether it holds outside the one case I looked at, and whether I’m reading the numbers right in the first place.
TL;DR: PureSci Labs might be fine, might not, and the way to tell apart seems to be documentation rather than price. Would appreciate other perspectives.

Batch-to-batch variation is the thing people underestimate. A passing result certifies one lot, not a product line, and vendors know most buyers do not make that distinction.
