Is my PS4 Controller Fake or Original?

Hello Everyone.I have a question.

I have a DualShock 4 Controller with Model CUH-ZCT2.Its working perfectly.I also have another controller that is copy and i can feel the pretty much difference between my copy controller and original(assumed) controller.I brought my PS4 2nd hand in good condition.That dude told me that Black controller is copy and second one that have a custom elden ring shell is original.

1:This controller performs very well and doesnt have any input delay like my copy controller.I played GTA V and other games to compare them and Original(assumed) Elden ring controller performed very well.

2.This controller joysticks also have firm resistance and it is very accurate and aiming is easy in games.its buttons are also good.And joysticks buttons L3 R3 also can be clicked and have a damp and different sound than my copy controller.

3.Unlike other controllers this controller has a sticker on which 1000MAh is written.Im not sure if there is any model that has written 1000mah battery as most of has written 800mah.I also opened it and battery is original 1000mah .

4.Its joysticks can also pop out(not out of shell) and snap back in.I have tried this on my copy controller but it has fixed joysticks that cannot pop out.

5.Im attaching pictures and videos of every single part of my controller.I have also attached videos with button sounds.

So please someone answer me if my controller is original or not.By my Point of View it seems totally original...
