I worked for Honda up until 2014 so rode everything I worked on and trade ins we had - so any litre to 14' I can help you on! (yes, even the awful RC8)
I'm no racer so I can't tell you what they're like on the limit or anything like that..
The Honda/Gsxr of that age are much of a muchness, nothing wrong with either. ZX10 is noticably faster, S1000RR feels faster still over the others (nasty clicky BMW switches though..!). RSV is a nice thing to listen to but under the fairings it's a real mess. I'm not even going to mention the crossplane R1... get one before that engine if you want a Yam.
Of that age I would have gone ZX10 as it's a real lary bugger (and green..) - I imagine the current one is much the same! Don't look so much at the 'race' tech on them, i.e HP4 bmw, you're not going to notice any of that on road.
I rode the first SP blades with the ohlins and brembos, felt the same as a standard one to me.. little smoother engine.
Depends what you're after bike wise, whether just for fun or longer distance? I like anything 10k rpm+, one of my favs was always a street triple R.. crazy little thing to ride but prob an effort on a long run.
Ask me stuff, there's a good chance I've ridden one and worked on them..
