Having owned a standard 8v, modified 8v and a 16v I can say the 16v is the quickest of the 3 by far. The standard 8v was pretty poor to be honest, it's not 1.1 saxo slow, but it's not quick. The modified 8v was more lively and it was great until just under 5800 rmp, then it lost the will to live completely. The 16v is a completely different machine. It loves being revved and the harder you push it the harder it rewards you unlike the 16v. It pulls very smoothly and evenly all the way to the limiter. The modified 8v would get a nice push at 3500 rpm till about 4600 rpm, then again at 5000 rpm to 5400rpm then give up 5800rpm. The 16v is far more progressive and feels smooth and even all the way round the rev range. Above 4000rpm it'll push you back into the seat pretty firmly and it'll happily delivery smooth linear power to the limiter at 6800rpm, without loosing puff like the modified 8v.
Here are the charts from the 3, look for yourselves. 16v, modified 8v then standard 8v.
