Same thing I like about the lasso and bracelets really, it gives her more variety in things she can do in a fight beyond being a flying brick and it looks cool in fight scenes. Lasso, sword, bracelets, that thing where she uses her tiara as a boomerang, that sort of tool and weapon use vs say Superman's many powers kind of adds to her uniqueness. Makes her almost a neat balance and mix of Superman (powers) and Batman (tools).
