Depends what you're trying to achieve. Turrets Pulse lasers for rapid fire, short-medium range. Beam lasers for long range high alpha lower DPS. Taychons (a type of beam laser) for very long range with high alpha. Extremely difficult to fit. Crystals (In order of range, short to long) Multifrequency Gamma Xray Ultraviolet Standard Infrared Microwave Radio Different crystals have different EM/Therm damage ratios. Long range Crystals do less damage. Some crystals require more capacitor than others. Faction crystals break with usage like t2 crystals, although they last about 4x as long.
