I would say it depends on the tactic used. There are those who are brilliant on the pole, but rubbish on the waggler, some who are good on the feeder and can't use a pole. So, is there such a thing as a 'best' fisherman?
If I was pushed to pick one from the site, it would have to be Danny (Halton Dangler).
In all seriousness it’s a very subjective question and not everyone posts reports so it’s hard to tell. Halton dangler is a very good shout though, a proper allrounder with video evidence of his successes makes it hard to argue against.
