So this isn't a thread about who the strongest in the series is. This is a thread about who you see making the most out of his or her abilities.
I'll start off with two examples
Luffy is an extremely good fighter who invents new techniques (Gear 2-5), figures out how to beat opponents (Crocodile, Katakuri). He learns from his opponents (Soru, Future Sight, CoC coating) mid fight and he adapts.
Queen is perhaps the worst fighter in the series. He has incredible weapons, one of the toughest defensive devil fruits, is old and experienced yet fights on the level of Jango.
Others worth mentioning is Kyros (fights to straight forward, lacks finesse to go with that strength and speed) and Cracker (makes the most out of a limited body and a limited ability, shame he's got PTSD regarding wounds).
