Of course this is just my opinion but i would set up the ships as such
Pyra-Most popular kill ship, very rare support Straight up play, good for any starter pilot and devastating in experienced hands, easy to crew easy to fly,
Goldfish-Mainly support ship with hawatch/carronade front for disable, very easy to fly, once you get more experienced with the ship can turn into a kill ship with side gun play,
Junker- In theory with the right build this is the perfect ship, with a good balance of long range and brawler, i would say this is the intermediate ship because you need good knowledge of weapons and angles to really maximize the damage this ship can do, also the ability to use the trifector long range and ability to switch to brawler side on the fly,
Galleon, The big hitter of the group, this is a hard ship to fly you need patience as it is not a fast ship the angels are smaller and you need knowledge of heavy weapons and practice to perfect a build that works on most maps and a good crew to fire the lower heavy guns especially if you go flak lumber jack long range, if you have the patience to learn this ship though you could be invaluable to any team comp,
Mobula- This ship is still establishing itself in the competitive side of the game at the moment it is the counter to popular junker builds just because you can get 4 weapons firing instead of 3, so this is a very good ship and popular with sniping captains on the more open maps like fjords and dunes, i don't think the flying of the ship is a problem more than the awareness needed from captain and crew as all the weapons are forward firing you need good positioning otherwise it will be a rough time also the captain needs good tool knowledge because hydrogen chute vent are essential especially against forward charging ships,
Spire- In some peoples opinions the most powerful ship in the game atm, you have 4 firing weapons similar to the mobula except one of them is a heavy weapon meaning it can take down anything and everything, it does have a major flaw and that is armor it can give out a lot of punishment but can not take much, meaning most people like to go mid-long range builds, it is very easy to fly but again the awareness of enemy ships and map position is the key factors to success here great for any pilot to try their hand at if the have the patience similar to the galleon when mastered this ship is devastating
Squid- Save the best till last, the majestic squid this ship is everyone's worst nightmare in the hands of a experienced captain once in close this ship will have you cursing the day it was developed, the hardest ship in the game to fly because all of the following have to be taken into account-Map Postioning-Every Ships blind spots- Map Layout and cover-tool use and when-good crew- Knowing when to run- Avoiding Fire- Knowing who to target first-Communication- BUT.... all that being said their is no better feeling than circling a ship knowing the balloon is down everything is on fire the engineers are drinking moonshine the captain is crying in the corner shouting WHY DID NO ONE SPOT IT!! and the hearty evil laugh from you're crew I would avoid this ship until you are ready for one of the hardest challanges to win with a squid on any map against anyone i know maybe 2 pilots who could possibly pull it off,
