If you're melee, maneuverability is the key stat you need, so the faster the better (in most cases). The best "happy medium" jets are actually the Protectorate and Aegis cruisers, in my opinion. Otherwise, you've got a choice between the Shark and the Glow. Personally, I prefer the Phaser, because it's very fast but sports medium parts and isn't as weak as the Torpedo.
The Devastator's plasma cannon is pretty great, since it's basically a weak plasma grenade with a smaller AoE, as long as you don't mind using one fusion cell per shot.
