Both sides cite plausible reasons, neither runs the same queries through both engines on the same corpus, and the conclusion is whichever one the author shipped. With identical data and identical queries you can measure exactly where each wins.</p> <p>The result: FTS5 and Vectorize have non-overlapping strengths. The right answer for most knowledge-base workloads is &ldquo;ship both&rdquo; behind an opt-in flag — not pick one. This page is the measurements, the cost math, and the dual-engine pattern.</p>
