The Ferret is faster, has a smaller profile, and almost double the armor plating. The two advantages that the epee has is it's I.T.T.S and Missiles. You could argue Particle Cannons also, but I prefer the Ferret's Mass Drivers in WC2 as they have a better firing rate. As far as looks when I first flew it in game back in 1996 The Ferret was like a cross between the X-Wing, and OG BSG Viper.
Yeah, on paper the Epee has some advantages, but in practice, the Ferret is more survivable and hits harder. And with the Super Ferret, it even gets missiles.
