Antarctica is 10x worse than aptitude, its less advanced and doesn't have RCS on DMR's, not to mention Antarctica keeps copying aptitudes Ideas this can be scene multiple times with Weapon Detection, Triggerbot, Screen Magnification and a lot more things. Just to give you a clue on how advanced aptitude is, Antarctica's system to switch your recoil to secondary is looking for 1 and 2 presses on your keyboard. Aptitudes is looking at your screen to see if you have your pistol or main equipped [ also works with C4, Mav Torch, Osa Shield, and a lot more ] as a user of Antarctica and Aptitude I would easily say my money would go towards aptitude.
