This is what I think it's like... Lucy is quite a strong wizard. Knowing she has 10 zodiac keys. Zodiac keys are known to be the most rarest, most powerful spirits to be known. If Lucy had mastered her celestial wizard magic, working together with her spirits, she would literally be unstoppable. And to Juvia, Juvia hasn't shown much of her full, inner most powerful magic power, we don't know if she has to ability to go to full strength. I believe Lucy can master, and contain all to her full strength. Especially with her spirits, I think she would go before Juvia. Here's how I think it would go:
