Sora Bulq's moves are agressive and although Soresu doesn't have a weakness, Vaapad is probably the closest thing to it. And Sora's a more powerful force user. Plus even if she managed to defend herself, there's little she could do to actually hurt Sora.
So if he tires himself out over trying to breach her defenses, and she takes advantage of it, then she wins. But if he can conserve his energy and be smart about his use of the force, then he wins.
I'd give the likely possibility to Sora Bulq.
