2004 Preddy, bone stock vs. 2003 z400 w/ full yoshi pipe,barnett clutch, holeshots

which would win a drag? for 300ft? for 1/4 mile? for 1/2mile?
which would do better on a track?
Which one is easier to jump/ has smoother landings?
which is better for trails?
which is a better deal? (cdn$$) preddy-5250, modded z400-4000

 

The pred has better suspension and more travel, it is stronger than the z400 but im not sure what one handles better. I think the pred tops out better and it should win any drag race against the z400.
