C205 has better weaponry, better ammo load, better climb rate, better top speed, better acceleration and raw horsepower, and still turns pretty damn nice.
Even in turn radius, they aren't too far off. The Ki61 turns almost like a hurr/spit, though, so it's not a fair comparison. The C.205 turns as well as most of the planeset (not counting the spits/hurrs/top 1% planes.
The only real weakness, IMO, is the strength of the 20mm guns on the 205, and the much shorter range.
