I think as far as readers are aware, Arthur Dayne is the best fighter. But, his death is a bit lame. IIRC, he dies alongside two famous Kingsguard in a 3v7 against Ned Stark and Howland Reed and some of their fellow knights. Ned isn't particularly known for being an incredible fighter (unlike his older brother) and Howland Reed didn't have much of a reputation except that Ned regarded him highly.
Considering Dayne's reputation and the reputation of the Kingsguard (Ser Gerald Hightower was an exceptional fighter too), Dayne's death seemed underwhelming. That gives me the impression there may have been better fighters.
