Sairaorg is not talented but has becoming strong as hell and is still becoming stronger.

Sirzechs is gifted with incredible talent but he is from his mentality not a trainingsnerd (and with his Jog and Family neither has the time nor the passion for it).

Rias is very Talented (I think we can say less than her Brother but still remarkable Talented) and she has a reason to train...so while not as much talent as her brother she can close the gap with training and the Desire to be stronger.

Will she surpass Sirzechs...ask in 500-600 years when she is the Age that Sirzechs is now ;)
