I would also like to add that for all intensive purposes Rose and Kensei were not actively fighting for over 100 years. I am sure they trained now and again and occasionally used Bankai to stabilize their hollowfication powers, but considering they are not really on active duty until about 18-21 months ago. So, its understandable that they might be a little "rusty." Plus Renji, who has been actively training pretty much throughout the entire series and in addition he has been training with some of the strongest and influential Shinigami in history and the fact Mask is...well not the brightest arrow in the Ice Palace, Renji has a clear advantage. Plus its about damn time Renji's hard work paid off.
