Both the Montante and the Tridente suffer from resembling oversized fighters and always look worse for it- part of it is the "cockpit" design of the command-center rather than a far better looking bridge design. These are gunships; light capital vessels built for the purposes of patrolling and escort- not fighters that ate too much cake. To that end, the far more gunship-style designed Bident gets my vote, though the giant axe-blade on the front that serves no purpose should probably be scaled down a bit.
Also: the opening at the prow of the Bident seems to make it resemble it's namesake, kudos points for that. Possible space for a forward gun maybe? Half the gunboats in the game have them so why the hell not?
Edit: changed some words for clarity.
