PE gets a bad rap and for very correct reasons (especially at the large cap where financial engineering is rampant). However, there are a ton of examples where PE does add value and the customer experience improves. However it's impossible for me to list them because your definition of customer experience improvement might be very different than mine. So this point is generally very moot unless we can all agree on a standard quality metric for "customer experience".

Go ahead and give some examples according to your personal metric for customer experience.

Good customer experience is generally associated with receiving good value for the money, and not feeling like you're getting screwed.

Can you list some anyway? I'm curious about your perspective
