Never timed them so I can't say much except 'similar' power.

I rode the GPz more, had it for a year longer and it was quieter and more comfy than the Katana. I could feel the GPz's extra oomph after I put in the 1166 kit, not a ton but nice to have. The Kat was not stock, with that Kerker and re-jetted, it was putting out great power but you needed to wring its neck a bit more. That very loud Kerker dissuaded me from opening it up WFO, it was just annoying to me and others. So in normal riding the GPz felt stronger.
