Spathion, Paramerion, and Long Espada are all good choices. Worth the extra cost, they have the reach/speed/damage that cheaper weapons only excel at one or two of.
Personally, I prefer weapons with 80-95 reach. Longer 1H side swings seem to have a habit of getting caught on allied bodies and walls.
Side Sword, Langes Messer, Italian Sword, and Broad Short Sword are my personal favorites.
Don't forget to pack a rondel dagger or other daggery knife thing. If you are built as a 1H swashbuckler they can deal out serious damage with unmatched speed. And what's more humiliating than being killed with a cleaver?
