rapier is the best vs heavy armor, because it has stab attack and melee armor have low defence vs stab
not at maxed PVP the CLS is easily the best melee weapon followed by the CCB
the CS is totaly useless now, Poly+Armadyl spells are better and you can still barrage extremely effectively with those staffs
CCB is probbaly the most versatile chaotic weapon, you can use it for high level pvp, bossing or even slayer it is without doubt the BEST VALUE
Rapier, not much to be said its a low level PVP weapon and PVM weapon, with less bossing potential then all other chaotics except CS
the CLS the most powerful chaotic ( DPS ) is THE best for high level PVP, non-ranged bosses, CR or CCB are slightly better in slayer or low level bosses A.K.A mole
the CM perhaps the most over rated weapon of them all this weapon only has 2 uses Waterfiends or PKing, it has a high Hit Potential but has the lowest DPS due to its slowness, the maul excels in low level (under 110) pvp and only the brawling gloves are better for waterfiends
ive had all chaotics on 2 accounts now if i had to choose them again in this order
for bossing CCB
for bossing/PVP CLS
for PVE CR
for Waterfiends CM
and i would not purchase the staff again and only the maul if i was leveling dung and has spare tokens
the Arcane Steam is a must buy along with wasteless herblore
