I was thinking about this, and the car analogy where they'll all start looking the same due to aerodynamics, applies here. The human hand isn't going to change, so controller designs are starting to look similar.
You can't have ideally placed analogs, since it would take too much away from comfortable button and D pad placement. So, you need to move a little up or down from the analog stick placement "sweet spot" on each side.
Nintendo's Wii U Pro controller has analog sticks that are a little high from the sweet spot on each side. High left High right.
The DS4 is a Low left, Low right.
The Xbox360 is a high left, low right.
The new Valve controller has it's trackpads set in the sweet spot on each side, but needed to sacrifice face button access to pull it off.
The DS3 had analogs that were low on each side, but ALSO too far to the center of the controller, making them worse than if they were just a bit low. The controller was also too small, made of a slippery plastic, the analogs also lacked grip, and the triggers were not shaped correctly. All adding up to terrible ergonomics in games using the analog sticks.
Meanwhile, in the Xbox360 controller, DS4, and Wii U pro controller, they all have analogs close to the sweet spot, just adjusted to be a little bit low or high, for access to face buttons and the D pad. And they all feel acceptable ergonomically in games using the analog sticks, they're just handling the problem a little differently.
