The problem with the Ody is the fact you can only ever train 2 TLs at on one target. The 3rd kinda gets wasted unless ther happens to be something else for it to shot within it's arc. Depending on the situation, you gte a Firepower efficieny of 6 or 9 OP per TL. You do make up for it in speed and easier targetting (since they are all turrets).
Paragon with 4 TLs is 6.25 OP per TL and can concentrate all 4 on one target or attack up to 3 targets at once. It also doubles as a meatshield if it becomes the focus of attention. You lose out on flexibility though, since 2 of the TLs are hardpoints. With the Paragon's low speed and agility, bringing the 2 hardpointed TLs can be a chore. You also concentrate more of the first from one point insetad of spreading it out more with the Ody's.
Well, either method is valid. I prefer the Paragon path since I can still plack plenty of firepower on it just in case it needs close range defense. The biggest problem I have is making sure my Paragons always have a clear line of fire, especially after the first wave of kills. Having a pack of Buffalo mk2s or freighters carcasses blocking the line of fire sucks when I still need/want to kill stuff behind them. I do space out my Paragons though, so usually at least one of them has a clear shot. (Otherwise I need to play bumperships with the dead ones and push them out of the way.)
