The question is not if Saba won't surpass Gura, because she won't
The question is if Biboo will surpass Gura. Which sounds ludicrous, but it is like say Jackie Chan surpassed Bruce Lee. Was Lee the superior martial artist? Of course, and his fight with Chuck Norris proves it. But who has the most movies? The wider acting range? The bigger influence in entertainment history? Jackie Chan, by nature of sheer output and experience.
If Gura was Bruce Lee, Biboo is Jackie Chan.
