You cite cutting power as a factor & then say the curves distract you. The curves dictate the blades ability to cut effectively.
It's not the existence nor absence of a curve itself, it's the aesthetics of the curve, the type of curves. I just find it looks too wavy and naturalistic. Katana just looks like it's from the future, even though the design is hundreds of years old. It looks like a refined killing machine for a person who has trained their mind body and their very soul to kill effortlessly.
I have no idea which intrinsically cuts better but have you ever the phrase "it's not the arrow, it's the Indian"? At the time the western world really became familiar with Japanese weapons the samurai were the most pre-eminent sword fighters in the world, that (artistically speaking) infuses the weapon with a reputation. It's as much the swordsman that comes with the Katana that makes it so sought after.
A western style cavalry sabre - to me - leaves the impression of a guy with a huge moustache yelling CHHHAAAAAARGGE while impotently waving the sabre over their head.
When someone twirls a Colt Single Action Army revolver you get the impression of speed, and effortless accuracy... might not be the case but those that have wielded it before in fiction and non-fiction have left that reputation.
Consider the Japanese samurai films like Yojimbo and the Seven Samurai that have imbued the sword with a great potency. And when we are talking about art, there is that wider cultural impression that counts with not only the audience but the characters within the work. In Pulp Fiction when Butch is selecting weapons to face down some armed rapists nothing seems to instil more confidence in him than a samurai sword, more so than even a chainsaw.
