Pist controller fake?

I found a ps4 controller on ebay classifieds.

I used my very old one and mine was the v1 and the other v2

I've had my controller for so long and the stick is a bit different from the new one.

The v2 controller looks real 1 to 1.

Is the controller from the other fake or have I had my sticks for sooo long (5 years probably).

Joo could be. It was the same for me with my brother's Ps.
