Experienced players

Why do experienced players who are actually very good at the game hate some specific weapon and weapon types? For example, I've seen hate on the Kusarigama Category while I seem to both enjoy it and destroy enemies with it, the long range can be a bit annoying when the enemy is 2 inches away from you tough you can roll away. Composite sword is another one for example. I mean I don't mean to say that I disrespect your opinion but I am curious as to why?
