I never dynoed either of my bikes, I'm just going on published hp numbers that were reported by the manufacturers for whatever those are worth. One thing I can say, the busa sure feels more powerful to me. I mean sure the ZX-14 with a +4 rear sprocket and over 75 lbs removed from stock weight jumps into action at any speed but the busa, with just a pipe and very few other weight loss mods still wheelies at a much lower rpm and that's stock gearing. The busa will also lift the front up by surprise while still in a lean coming out of a corner. The 14 will too but I have to try to make it do that. The busa is more wheelie prone if you ask me and I'm attributing that to higher torque. Your racing experience with both is more valid than my seat of the pants experience riding them back to back but I still have a little more fun on my busa.
