Airman
That is the G.59 i don't think it performed better. Maximum speed was worse but it wasn't developed to be a combat aircraft.
But some were sold to Syrians for combat. In Italy both monoposto and biposto versions had only training propose.
post war G.59 had 1100 hp derated Merlin
rumors say that Pino Valenti G.59's , with a non-depowered Merlin, has reached 700 km/h
about G.55/56 you can consider that they are the same aircraft, the only difference behind/firewall is the false rootrib nose is open forward by 8°16'18" in order to allow to move the engine (DB603) about 1ft backwards to preserve the balancing occupying the space previously intended for ammunition tanks, this is the reason why machine guns were eliminated... a wing with 4 guns was already planned; modification maintained on g.59 even the weapons were mounted in a single sample...
