How do you win gunfights now?

I've been an Apex player since day 1 but never reached & passed 1.0 K/D until S6 & have since currently reached 1.2 K/D.I was a regular player often putting in up to 2 hours a day up until around S12 but since then I just put less & less time into the game where I'd often go days even weeks without playing Apex & just play other games instead just through sheer frustration of the slow & often  non-effective attitude to fixing bugs in the game.Since S14 I pretty much gave up on BR & just preferred to play Arenas because of how bad the general MM felt in BR & so my 1.2 K/D ratio was mostly earned up to the start of S14.Even if I attempt BR (pubs) a bulk of the matches just feel like squash matches nowadays where it seems I'm pitted against lobbies of  pre-mades & predator squads & that's before  considering that I'm often already a teammate down at the start of the match & even once landing I am often struggling to find any other weapon other than a P2020 & or Mozambique no matter where me & my teammates land no matter the map everywhere just feels like a hotspot nowadays with very little to defend yourself at times.

As much as pro players & M&K players complain about the 0.6 aim assist us console/controllers have for me as a PS5/Xbox X player it just has very little if any advantages at all weighing up issues with weapon recoil of weapons,using weapons without scopes,muzzle flash etc.I did hear from various sources that if more than one enemy is on the screen aim assist can be a disadvantage.I certainly agree with other commentors that any advantages that controller players have would be down to any strike packs or any other assistance devices players may use to gain advantage & certainly not us players who don't use these devices. It's the overuse the overly excessive tap-strafing advantages of M&K players that I regularly see & am up against has a much more negative impact on the game than any miniscule aim assist advantages us controller seem to have.
