Certainly, styling is a matter of opinion. I just don't agree with certain claims about performance figures. If you have two planes, both say 1000kg, both having say 180HP, and both having a VP prop, and both having the same stall speed, then both will have a very similar takeoff run and initial climb performance.

This is because, at speeds low enough for drag to be relatively less important, the acceleration is simply some constant multiplied by thrust/weight. Also when you get airborne, you are still flying slowly, so the climb rate (+fpm) will be similarly determined because you are converting engine power into potential energy.

The bit I underlined is the key to differing takeoff performance given the same power, and this is where loads of compromises in cruise speed, range, etc come from.
