The Ninja's take
2 out of 5
$69 for a database that says "millions" of creatives while BigSpy has a billion and a free tier. No stated date range, no limits, zero reviews, which on a data product means you can't tell what you're buying. The Winner/Loser score is "99% accurate" against a truth nobody outside the advertiser can see. Useful only if you ship a mobile game. Pass.
