What is the best weapon mod to run?

For a really long time Icarus was the go to, but after the initial AE changes people swapped to quick access sling, backup mag, and target adjuster on controller. I know that AE has been significantly reworked and with the In-Flight Compensator mod on the helmet you can stack it pretty high (although I'm not sure how many to stack on the helmet. Like is the meta one of those mods and then one of each of your primary and secondary for targeters?)

Basically what I'm trying to ask is "is icarus the default go to on all weapons, or is adept range on primaries or adept handling/quick access sling on shotguns for example still better?
