It’s one of the messier options but it still works well. The switches in my logitech g604 have been bounce free for over a year now after hosing then down with WD-40. That’s longer than any of the warranty replacement mice lasted.
Deoxit leaves a residue, too, that will stain clothes. That residue is what helps the contacts from oxidizing again in the future.
That is kind of just how non hall effect thumb sticks are. But I’ve had great luck with Deoxit D5. You have to take apart the controller so you can squirt it directly into the switch itself but as long as it’s not a mechanical problem like a weak spring, the Deoxit usually gets it working like new.
Really depends on the game/story and if I like the characters. For example playing Fallout 4 as a female protagonist felt out of place, like it was just a mod that someone hacked in. But on the other side Cyberpunk 2077’s male character annoyed me enough that I restarted as female V. And then there’s games like Skyrim where the only difference I notice is the grunts you make in combat.
