The weight difference is debatable, I've seen it listed as, from 100 to 500 pounds.

I am very biased here but I know for a fact that the Super will out do a Standard in handling. When I was in high school, me and my best friend both had Bugs that were set up exactly the same. Mine was a 1973 Super, his was a 1974 Standard. We both had stock motors and a lowered suspension with aluminum wheels and 195/50R15 tires. My car would literally leave him behind by 3 to 4 car lengths in the corners and the smaller turning radius of the Super made it easier to maneuver overall. We would even switch drivers and get the same results.

The other factors to consider are... that the Standard has a wider rear track (like almost all pre-70's cars) and the Super has a wider front track (like all post-70's cars). The Super has struts (like 99% of modern car designs) and the Standard has torsion bars (0% of modern car designs).

I've said it many times before, the Standard is a great car for straight-line drag racing and the Super was made for autocross/corners.
