The WizarSword Gun is a far superior weapon to Sword Vent and Strike Vent since it can quickly switch between long range and melee attacks and has it's own finishing moves, so Haruto has the advantage weapon wise. And if Haruto starts using Connect to attack Shinji's got no real counter move. As for if the two dragon's fight, the WizarDragon would seem to have the advantage since it can combine with Machine Winger and team up with Haruto to attack. If it comes down to rider kicks, I'm pretty sure Wizard's Giant Dragon Claw kickstrike will cream Ryuki's Final Vent.

It seems to me Wizard has the pretty decisive advantage here, though I will admit my knowlege of Ryuki's abilities comes mostly from Decade and Dragon Knight.
