I'm probably missing something, but i can't find a reason to use rocket turrets.
Rocket turret and laser artillery are at the same research tier, but Laser artillery makes Rocket turret look pointless.

Rocket turret:
+A lot of area damage(like... ridiculous damage)
-That damage is mostly wasted on forward running biters.
-Very expensive ammo
-Only 80 range
-Needs ammo suply chain

Laser Artillery:
+200+ range!
+great single target damage, decent area damage
+uses power only, at this point in game, it pretty much means it's free.
-less damage than rocket turret(longer range negates this easily).

What am i missing?

That u need a source of energy to work? (even where u can't connect one [outpost?][logistics?])? That need a LOT of energy? And can't kill modded biters that are resistant to laser damage?

But the most important thing... "Style over Substance", is more cool :)

The best 'Style over substance' are Krastorio gun turrets. ^_^
A row of gun turrets, spitting led, with every bullet visible is amazing and i love it.
