Not 190 vs 47 but as regards 190A having less drag.... Compare the F4U-1 and
Fw190A-8. The power is practically the same, 2000hp on the deck (F4U mil pwr
and 190 Special Emergency). The 190 is only about 10mph faster on the deck
but the F4U-1 has some 60% more wing area and 20% more weight.
Doesn't speak well for the 190 being sleek
"Sleek" is usually consistent with a low coefficient of zero-lift drag, not necessarily just a big difference in speed. A FW-190 will out accelerate an F4U-1 very quickly, so not only does it go 10 mph faster (which is a big enough sea-level difference to matter), it gets up to that top speed faster.
Again, the acceleration and top speed are functions of power available and power required. When power available = power required, an aircraft is either not accelerating and level (top speed at that amount of power), decelerating and climbing, or accelerating and descending. In order to accelerate while staying level, there must be excess power available. If we consider thrust to both aircraft equal, then the F4U-1, with its higher weight and Cd, has a higher power required to accelerate compared to the FW-190. So, both the difference in acceleration and the difference in top speed demonstrates that indeed the FW-190 could be considered more "sleek" than the F4U-1, assuming thrust is equal.
Of course, assuming thrust is equal, just because the horsepower of both aircraft is equal, is another assumption that can get you in trouble. Differences in the propeller efficiency and exhaust thrust realized by either aircraft can introduce another difference which should be considered in a comparison. It could be that Kurt Tank optimized the FW-190 prop for one flight regime and Vought optimized the F4U-1 prop for another flight regime.
TL;DR: Thorough aircraft performance comparisons demand very detailed analysis. Cherry-picking one performance metric and basing an entire comparison on that metric can lead to false conclusions...
