They just can't be compared to a Zed.
Scooby STI is a turbo rally nutter saloon car with 4WD. The EVO is a turbo rally nutter saloon car with 4WD and the tommi mak is desirable, collectable and AWESOME!
The Zed looks a hell of a lot better but doesn't go as much, doesn't grip as much and has a torquey NA engine with RWD.
I'd advise driving all the cars to see what you want. If you want a thump in the back get a turbo nutter. If you want a good looking GT car with an exploitable chassis then get a Zed.
