The missiles had different firepower and speed/agility depend on their lock type. IIRC:
FF: 280 cm damage, slowest missile
IR: 360 cm damage, faster than FF, twice as hard to spoof as FF and HS
HS: 450 cm damage, faster and more agile than IR, but the most agile fighters could shake it by turning quickly enough unless it is launched at point-blank range
Artemis ELRIR (Prophecy/SO): 620 cm damage, faster and more agile than IR with twice the range
DF: 800 cm damage, fastest missile, no guidance (flies in a straight line)
