I have not played far enough/have not played the second game to know what these are. I will go with Glaive.
Rosaries are the most fun to use because of the extremely high combos, ease of use, and also the ability for a proper ranged attack. EDIT: For everyone!
Reflector is like, lemme beat you with this mirror for a sec, okay done. Glaive is like, I'm a wolf with a sword, no big. Rosaries are like do a 64 hit combo, get the same damage as a four hit combo with the other weapons.
