Ffion Davies and Nathalie Ribeiro have met 6 times on record, with Davies leading 4 to 2. Both compete at Peso Pena, 58.50 kg, so this is a true same-weight rivalry rather than a matter of size. The split runs along a clear line: Davies took both 2019 IBJJF meetings at the 2019 World Jiu-Jitsu IBJJF Championship quarter-finals and the 2019 Pan semi-finals, and both 2021 no-gi meetings at WNO by decision. Ribeiro answered in 2022, winning both meetings at the Pan, once on points and once by submission.

The styles read differently in the numbers. Davies has 67 wins from 85 recorded matches for a 79% win rate, and finishes 55% of her wins, most often with the Armbar, her top submission with 15. Ribeiro sits at 37 wins from 56 recorded matches, a 66% win rate, and finishes 24% of her wins, with the Kneebar as her most frequent finish at 2. So Davies carries both the higher volume and the higher finishing threat over the recorded sample.

What decided the meetings tracks with format and timing more than any single technique. Davies controlled the earlier IBJJF and no-gi bouts, deciding them by advantage or decision, while Ribeiro's two wins both came at the 2022 Pan finals, the only stage where she closed the gap. Against shared opposition the two look close, splitting results against names like Beatriz Mesquita, Bianca Basilio, and Talita Alencar in different directions.
