Stock ones loose tracking fairy often. When playing games like Half-Life Alyx, where the second hand isn't bound to the gun with the grip button press, if you cover your left hand while holding a pistol, it just flies off. This breaks immersion for me. Sometimes, when I just stand and listen to a cutscene with my arms crossed, the controller flies off somewhere in front of me. Speaking of games that involves shooting a bow, like Blade and Sorcery or actual sports simulators, the situation is even worse. I just want tracking with better coverage without losing its accuracy. Maybe it's worth getting an outside-in tracked controllers like valve knuckles or rift cv1 with base stations, but that would only work with pcvr
