Power to weight is not the only indicator -
TVR Sagaris - 371 hp/ton
Corvette Z06 - 350 hp/ton
but the Corvette is much more torque (637 Nm vs. 473 Nm) and chassis tuning, and as a result - it is faster.
Look and sound, this is not an objective indicator - How many people, so many opinions.
Personally I like the simplicity of appearance of the American automobile.
Sound of the V8 engine, better than the V6
