Serena can play more aggressive than Kvitova, there's no doubt, but this not about ballbashing potential, it's about what they do on the court. The thing is that Serena has options, while Kvitty's options are limited. For sure she can improve her defense (like Ivanovic did in 2008), but she'll never reach Serena's level in that department. Her fitness is a huge issue atm, so she's forced to finish the point fast. Serena rallies more often and with much more success.
