Higher pitched more like an F-1 the Honda hands down.

More throaty deeper rumble the Kawasaki. Did Not look it up but wunderin which one revs the highest. In the 60s had seen some factory works bikes testing if I recall near Mt. Fuji. Pick a brand. I remember some of the loudest engine screams I've ever heard in my life then. The revs they were pullin were fantastic. RIDE SAFE.
