Our assessment, based only on the checked statements above.
We checked all 4 alternatives on this page against each company's own website in September 2026. Every line in the grey panels comes from that company’s own site, and a second check tried to disprove it before we kept it. A dash in the table means we could not verify that detail. "Pick it if" lines are our own assessment, based only on those checked statements.
