On a serious note, the Triumph Daytona 675 is an incredible bike. The 3 cylinder is great. The bikes you listed are all very different. In all honesty though, if you get a 600cc you're eventually going to want to go 1000cc, it's like the guys who say they're not going to chip their GTI because it's fast enough...the feeling doesn't last long.
I would go with the CBR, It's a great bike, and Honda engineering is second to none. If you want to be a bit different, get the Triumph, you don't see many of them, and the engine and transmission is pretty impressive, the chassis...not so much. I was kidding about the Ducati by the way, the thing is a pig.
One more thing, the Kawasaki ZX-6R is hands down the most neutral bike, it's down on power, but the chassis is amazing. If you want something easy to ride with enough power to get you in a lot of trouble. Go Ninja.
