Where they differ

On the 20capabilities we track, we found no case where one of these does something the other verifiably doesn't. That is a real finding about how close they are — not a gap in the research. Compare them on price, engine coverage and the company instead.

Not published is not a no.Where a vendor never states whether it does something, we say so rather than printing a verdict we can't source — so an empty-looking row is a gap in their documentation, not a missing feature.
