Category evidence
We do not know, and we will not pretend to. Ranking software here would need five products each carrying eight verified first-party reviews. Today 0 products are scored, so any ordered list would be opinion dressed as research.
What follows is the evidence for all 8 products in this category, unordered, with the “best suited for” classifications the data does support.
Verified against the vendor’s own pages.
Why this page is not indexed
This page carries a noindex directive. Blocking gate on record:
G-data (no scored products until reviews land)
This category holds 8 products, so it can clear the five-product gate once reviews arrive. That is a deliberate constraint, not a gap to be filled later with an opinion.
Blank cells are excluded from the denominator, never scored as zero. Vendor claims count at half the weight of verified facts. Products whose surface we could not read are not scored at all. And the publisher’s own products are excluded from every ranking, permanently. Full methodology
Listed alphabetically. The ordering carries no judgement.
