It would be interesting to see a breakdown of shared / unique entries across the different competitors in this space.

I have a feeling that there would be overwhelming overlap.

That might not be bad, just low hanging fruit everyone can get.

The speed at acquiring high probability threats I guess would be a better / more valuable comparison.

Perhaps running two or more of these offerings side by side for a couple of months.

I would prefer a feed of ALL, with frequent updates, instead of querying a 3rd party every time. (well obviously you can cache responses for a period of time locally at least)
