You are comparing apples and oranges there, matey. And you haven't mentioned your budget.
The bandit is a great, fun bike, comfy and capable in a budget sort of way. They are not well protected from weather so avoid any rust buckets and don't use it in winter. If you have the extra cash, a 600 hornet might be a better prospect.
If you want a sports bike, you can't go wrong with the cbr but the later models get more seriously sporty.
ZZR was ok at the time but looks seriously dated now. And heavy. Good strong kwaka engines though.
