Head to head
Babolat Xcel French Open Black 16 vs Gamma TNT2 Rx 17 (1.25)
Xcel French Open Black 16 leads on 4 of 6 measurements. The widest gap is ball bite, where Xcel French Open Black 16 is 9 percentile points ahead. Every figure is a testing-machine result at a fixed reference tension.
Measured, side by side
Bars are percentile against all 788 strings, and the marked side is the one that measures better — which is not always the one you want. A firmer bed is worse for your elbow and better for your control, and no measurement knows which of those you came for.
Which one wins, by problem
Each string's standing on the site's rankings, out of every measured string in the database. This is where a comparison stops being arithmetic and starts being a decision.

Hybrid: what if you used both?
Estimated, not measured. No hybrid combination has been tested as a bed — these figures are the two strings' own lab measurements weighted by how much of the bed each one actually is. Treat them as a guide to which way a pairing moves, never as lab data.
