Genuinely the correct answer is the Keyblade. Sure the OG Keyblade looks silly but that fucking thing can do basically everything every other sword on here can without any of the draw backs like the Manado crippling you and Soul Edge turning you into a corrupted monster.

Gives you magic, makes you fly, can control Gravity and Time. I literally can't see any downside to the Keyblade besides it looking dumb but you can also change it to look cooler so that's a plus too.
