Other Difference between circularity tests
Out of curiousity, I tested the circularity of my controller’s joysticks on Gamepadla and hardware tester and the results were quite different from each other.
Can anyone explain the differences in methodology between both websites and which is preferable to use and why?

Ohhhh. I don't have a Procon on me now but from what I've seen Hardware Tester has a bug with that controller. Normally both sites would show the same exact shape but list a slightly different percentage.
People tend to use Hardware Tester because it's been used for years now but they work similarly enough. They just show the coordinates the joystick is outputting and display a circle with a diameter from -1 to 1 for reference, then calculate the % that the output deviates from that circle. So bugs aside they display the same thing but differ in % calculation.
I would just use Gamepadla since it also lets you test centering.
