What is the power difference?

Hey guys I have an 89 model ZX2R its in great condition feels very smooth and still has some great pull for a 250... Its in mint condition, but everyone I talk to keeps telling me its crap and I should look into buying a new ninja or god help me a stupid CBR... What I want to kno is what's the power difference?
Sure my bike doesn't look as sharp as the new ones but I like the round eyes at the front lol. Anf it sounds great with the exhaust on there...
Thanks Steven
