I will take this blueprint as oppertunity to compare each turret with another and tell, which turret is the 'top' turret for each aspect.

Aspects: Range(m), FiringRate(rpm), Accuracy(velocity), StorageEfficiency(rpm/stacksize), ResourceEfficiency(rpm/craftingcost), Damage(dmg)

Raw Data
Cannon: 925m, 300rpm, 16dmg, 6max, 70craftcount, 1500stacksize, high-velocity
Minigun: 850m, 600rpm, 8dmg, 6max, 100craftcount, 1500stacksize, high-velocity
Rocket: 1150m, 15rpm, 502dmg, 4max, 5craftcount, 100stacksize, low-velocity (+Guided)
FLAK: 1135m, 150rpm, 40dmg, 6max, 20craftcount, 500stacksize, mid-velocity
Plasma: 1200m, 8rpm, 1278dmg, 4max, 50craftcount, 200stacksize, low-velocity
Laser: 1085m, 150rpm, 40dmg, 6max, 120craftcount, 500stacksize, high-velocity
Artillery: 1100m, 5rpm, 2212dmg, 2max, 4craftcount, 50stacksize, low-velocity

Calculations (MaxAmountTurrets, Rounded up)
Cannon: 1800rpm, 28800dmg, 1.2stacks/min, [88-Iron, 5-PlantFiber]
Minigun: 3600rpm, 28800dmg, 2,4stacks/min, [45-Iron, 3-PlantFiber]
Rocket: 60rpm, 30120dmg, 0.6stacks/min, [16-Iron, 80-Magnesium, 80-Erestrum, 8-PromethiumOre, 40-Copper, 20-Silicon]
FLAK: 900rpm, 36000dmg, 1.8stacks/min, [40-Iron, 300-Magnesium, 13-PlantFiber]
Plasma: 32rpm, 40.896dmg, 0.16stacks/min, [32-Erestrum, 16-Pentaxid, 5-Corn, 2-Gravel]
Laser: 900rpm, 36000dmg, 1.8stacks/min, [10-Pentaxid, 5-Corn, 2-Gravel]
Artillery: 10rpm, 22120dmg, 0.2stacks/min, [11-Iron, 104-Magnesium, 104-Erestrum, 8-PromethiumOre]

Range: Plasma (1.2km), Rocket (1.15km)
FiringRate: Minigun (600/min) [3.600/min]
Accuracy: Cannon, Minigun, Laser
StorageEfficiency: Plasma [0.16], Artillery [0.2]
ResourceEffifiency: Plasma (LowQuantity), Laser (Renewable)
DamageSingle: Artillery, Plasma [DamageMax: Plasma, FLAK]

Personally i do prefer Cannon, Minigun and Laser Turrets, primary cause of the very low resource costs.
Especially Ls.BA-Ammo (Laser) requiring only renewable resources (besides rockdust).
