No stick issues so far. My DualSense's microphone seems to have issues and my Series controller's A button seems to like double pressing once in a while.

Same here never had a problem with my own controlers since N64, but i guess it's a combination of how the products came out of fabric, and also a lot of other factors including how you play with them, had some friends in high school that fucked up every controller relly bad:

- N64 analog sticks used so intensively they were totally loose, that they didn't even register movements.

-PS1/PS2 dual sticks from the dual shock stuck in position as if they were glued with something from behind, also the button from top of the analogs totally unpressable.

- Gamecube analogs destroyed in states similar to the N64 and PS ones previously described, i suppose from playing too much smash bros melee, but they were also capable of fucking up the gums?/plastic that are on top of the analogs as if they had been bitten or also completely removed, so when taking turns to play smash with that analogs felt like you were playing with a razor on your tumb, not as comonly but i also saw this done to a dualshock controller too.

Later i never saw/had problems with the analogs controls of any console, just the switch from some acquaintances that have the drift problem. 

My Dual Sense started drifting with Cyberpunk and still does. Tried resetting it and it hasn't worked. But it's not too bad as I can play without it affecting my gameplay. Gonna see how I get along as shipping cost to fit apparently isn't great.

No issues here! The Dual Sense is the probably the best controller from Sony in terms of build quality and feel in the hand. I cant imagine it having more issues than the PS4 controller...which really sucked in build quality. And PS3 and PS2 controllers had widescale drift issues from what I can remember...never became a issue worth talking about though.

No drift though.

The PS5 burnt my house down and the dualsense stole my car and entered it into a drift comp.

I've never had drifting issues on any controller either. D-pads, shoulder buttons, A buttons... With all of those and more I've had problems or known of someone who've had them at some point, but never with drifting sticks. In fact, getting to know that this is not something exclusive to the Joy-Cons and the DualSense feels almost like if I was living in a little bubble and then it just suddenly bursted.

Were you friends with the Hulk?

 It could be a boon, in my case a form of auto steer. Polyphony should label it a driving aid and great for drift comps, also imagine it in ridge racer.

 But in the end the last word would belong to Nintendo.  "don't use an inferior copy play Mario Kart and experience real HD drift ".

Tokyo Drift game confirmed?

I don't have any specific sources to link you to. My info comes from my understanding of manufacturing practices.  

When you hear talk of 4-5% being acceptable, that's generally something that doesn't impact the ability of the product to do its intended job.  So, on a video game controller, it might be something like the X graphic on the button is slightly misaligned.  Things like drifiting analog sticks essentially render the controller useless, and result in a return or a warranty claim.  For those kinds of things, you're generally looking for less than O.1% defect rate.  I manufacturing in general, the goal is typically <0.075%.

Note that I have not studied manufacturing of video game hardware in particular.  So, it is possible that a bit more than 0.1% is normal.  I see no chance that 1% is considered acceptable though. That would be hugely expensive, and expenses like that are not tolerated in modern manufacturing.
