The post also does not state level either so more info would have helped .
the truth is there is no best melee weapon , but there is a best weapon for different levels , at first things like agility and stamina rule over weapon type end game it might be + crit or + ap ( there has been so much said about different end game weapons and their stats i will not repeat it all ) but still i say the same thing , the type of weapon does not matter but the buffs always do.
All the way through to 70 i always used whatever Weapon had the best stats at the time i found them either in drops or at auction , I have used Guns , Bows , Crossbows , two handed Swords , one handed Swords , Daggers Axes , two handed Axes , staffs , polearms , for a short while i even tried some fist weapons , none were special apart from they were a decent upgrade to what i already had , At end game it all depends on if you are PvP quest or instance playing and i guess which tree your spec is also would have helped answer the question better...
