For Vergil, it's obviously Dark Slayer. Woulda been cool if they'd developed unique styles for him too. However, with Dante, I must say the style that I used the most was Sword Master, closely followed by Gun Slinger. Back then I was much more on the offensive so I never really had use for Trickster or Royal Guard. I suppose after having played DMC4 that if I were to play DMC3 again I'd take more advantage of the Trickster's speed and the Royal Guard's Royal Block move. They would probably save me a lot of time and hastle. ^__^
