For example. VT's are clear winners of AU's...
You can't be serious. I know this is a Holden forum and that the AU is widely reviled as the most butt ugly car ever produced this side of the the Iron Curtain [although don't mind the look of the AU Fairmont Ghia truth be told] but you can not honestly think the VT is a "clear winner" over the Ford with all the problems they had. Other than looks, and the VT doesn't set the bar that high either, there is no comparison between the AU and VT Commodores.
In general, I prefer the Falcon to the Commodore. It's generally accepted that the FG Falcon is better than the VE Commodore. Ford kept working on their I6 engine, going from 148kw in the 1992 EBII Falcon through to 157 in the EF series and up to 172 in some variants of the AU, and then 182 in the 2002 BA. The FG Falcon, develops 195 kw and apparently they could easily tune it for over 200 kw but choose not to, so as not to fall afoul of various insurance regulations and other laws.
Holden on the other hand stood still. Going from 130 kw with the VP/VR series Commodore, through to the 147 from the VS/VT and 152 from the VX onwards. It was only by supercharging the V6 that they had even a snowflakes chance in hell of competing with Ford, and one got the message they all but gave up. It's only with the VZ onwards that Holden has started to compete with Ford in terms of power again, and even then they compete in terms of kW only and not the equally important to me, at least torque figures.
