If you are talking 0-60 a petrol is normally better than a diesel with similar power in the same body. But when it comes to in gear accleration e.g. 40-70 in 5th the diesel turbo will always beat the similarly powered petrol in the same car, its down to the way the torque is produced.
Personally even if a diesel did cost more to run I would buy one since the modern petrols I have driven tend to be gutless beasts that need the nuts revving off them to produce decent performance.
The exception I have driven was the 122 bhp 1.4 turbo petrol in the Skoda Octavia, in truth I think it drove better than a diesel, no lag at all and great power all the way from 1500 - 6000 rpm with great in gear accleration as well, nearly bought one but an expected mpg of 35 put me off together with the deafening road roar even on smooth roads.
