I would concur w/ Steve's "not necessarily". The better car is largely a
factor of individual taste and need.

The C2 is the closest you'll get to the original concept, feel and
handling of the 911 in the current Porsche lineup. It's a tick quicker
than the C4 owing to the weight and additional drivetrain on the C4. If
you live in an area with perpetually slippery roads (ice, snow, gravel)
the C4 might be a better choice, but the C2 is certainly not afraid of
rain and other inclement weather.

The C4S has a turbo style body and is a gorgeous car; the C2 is a simple
narrow body and is a gorgeous car in its own way.

The trailing throttle oversteer characteristic of the original 911 has
been largely engineered out of the C2 and C4, but both retain a rear
weight bias so anyone intending to approach the limits of either car's
handling needs to be capable of dealing with oversteer. Exiting a turn,
the C4 might be able to apply full throttle a bit sooner owing to its
all wheel drive, but both cars retain the same overall handling traits.
The key to driving either car competently is balance and smoothness. Vic
Elford calls the 911 the "best handling  two wheel drive car in the
world on slippery surfaces, providing it has the right tires".

We love our 2002 C2!!!!!!!!
