Sir there is a lot of difference both in subjective and quantitative terms.
At least 2 seconds flat from 0-100km/hr on manual, if you want the numbers.
A VTI PROSMATEC can easily beat a Manual EXI no matter how good it is, in condition and how good are you in shifting the clutch.
Otherwise a VTI Manual on CNG can keep up with EXI PROSMATEC on Petrol.
The power difference will be very visible once you have passed the 150km/hr barrier.
The best part is that VTI 7th gen has ABS on all 4 corners and bigger tires with EBD to deaccelerate you safely.
Correct me if I am wrong, if you can buy any VTI up to 2006, the 1.8 has the most acceleration and shortest time from 0-100km/hr but the Eagle Eye Civic is easier to control and handle.
So I would suggest, you go for the 04-06 Eagle Eye Hardtop manual, but a oriel or PROSMATEC is also good if its in better condition then the hardtop as some people drives VTI roughly.
