I mean, first off, a lot of you are focusing on the right side joystick but it's completely irrelevant since it's the same position for both, I was just using it as an explanation why it makes sense for it to be assymetrical on the Xbox controller. I personally only play non FPS games with a controller so for me it's the majority, but I understand that maybe most games played with controllers today are FPS or use the right joystick more than the left. But, again, that wasn't really the main argument nor the point.

But second, idk man but how is your natural hand position such that it's easier to reach the PlayStation left joystick instead of the Xbox left joystick? When I look at my hand in a resting position, the thumb is right over where the joystick would be on the Xbox controller. The only type of game where the PlayStation layout would be superior when looking at that element is one where you mostly use the Dpad, like a fighting game.

I don't have a PlayStation controller with me right now, so maybe the body is differently shaped as to make the bottom joysticks the natural thumb positions unlike on the Xbox one, but on the Xbox controller your natural thumb resting position is definitely the top row.
