Its hard to sat they both put a smile on my face the 7 when the second turbo kicks in and pushes you in to the seat, and the noise of the rotors and turbos spinning up and the look of it as well. With the 8 its the third port opening after 6k the whole way the car changes into a different animal at this point and noise is great as well!
When i sort out the bushes and shocks on the 7 then the handling will be on par. If you are going to get an 8 make sure the coils are ok the difference between good and bad coils you can tell when you drive it there is no power at all as the wife said me before they was done she could not even beat a corsa away from the light!!!! lol.
