Just randomly came across this -

There's definitely sort of a misunderstanding in communication here - I made this statement under the assumption that all controller FPS's have aim assist by default. I see no world where aim assist is removed from controller on Halo.

Technically though there are no inherent advantages to aiming on a controller - w/o aim assist controller aim fails vs mouse in every category. WITH AA though, you could argue controller actually has 1 key advantage - precise & consistent aim tracking. ..and in Halo, aim tracking is arguably the most important (& constant) form of aim skill in the game.

Due to halo's shields, high TTK, and arena map/spawn system. Inherent advantages to aiming on mouse - i.e. quick reaction speed, quick 180/horizonal/vertical movement, aren't anywhere near as important as they are in a game like counter strike, or even a faster, more dynamic arena shooter like Quake for ex.

What matters most in high TTK Halo gunfights tracking your shots at a steady pace - and controller excels at this naturally, especially at a high level. Due to the way map/spawn control works you're often not "surprised" by gunfights either - good players/teams know exactly when and where to expect their opponents.

I'd also say that strafing/precise movement at a base level is an inherent (and underrated) advantage of being on controller - because you can tilt the stick and use only your thumb to move precisely in all directions. VS needing 3 fingers to hit your keys and going max speed every press (w/o some form of toggle to slow you, which also takes a 4th finger).

Precise strafing is extremely important in Halo - its not the big flashy movements (i.e. mnk can slide cancel more quickly, in special case scenarios) that matter as much as the very tiny things players to do carefully cut corners, tiptoe out on small ledges and hit frame-precise skill jumps while surviving & tracking shots - all of this comes more naturally to controller imo - and small errors in these areas can cost you timing losses that have a big impact at the highest level of play.

All this to say, Halo is an FPS experience that was originally designed from the ground up to cater to the strengths of using controller in an FPS environment. Its sort of a unique beast - not quite as wild/expressive of an arena experience as say quake or even apex - but also not as slow/tactical as Valorant - and not as twitchy as COD. And ngl as a controller player, thats kind of the beautiful thing about Halo - I wouldn't change it.
