In the technical aspect the OC already wins the KUB in terms of
horsepower. 299bhp VS 230bhp. The OC therefore accelerates much
faster than the KUB if given both the same driver to handle and
using the same force on the pedal.
But I also wouldn't say that the KUB is not a good model. Both
OC & KUB are good for its looks as well as in-vehicle comfort.
You wouldn't be able to find a stuffy KUB (unless the A/C spoils)
neither would you find one from the OC.
Stuffy/warm KUBs, experience till sian. As for OCs, always
freezers, never warm/stuffy.
And comfort level wise, I think OC beats KUBs hands down, but
this may be due to the aircon.
