Actually I said, underqualified, but whatever.

She was ranting like that because she felt she should be in the advanced class because she was smarter than Renji, but that wasn't what puts you in the advanced-class. Advanced-class is about being more balanced that most, and sure, Rukia has better skill intelligence and Kido-wise, but she zanjutsu, hakuda, and hoho don't even come close to Renji's level.

That was why when she was graduated early from the academy she was so out of place and needed additional training from Kaien, hence their whole relationship. But Renji ended up outperforming his seniors in the advanced-class by killing hollows during a training gone wrong.

Sure, Renji had Ikkaku, but Renji was still years in front of Rukia despite the natural skill both had. Rukia isn't bad, both her and Renji achieved Bankai despite only being slightly over 100+ years old. That's not small feat considering how long it takes the normal soul.
