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".
I use ASP for my pool cleaning and they referred me to their electric company (Mr Sparky). Both have been excellent services and I was able to receive a discount on Mr Sparky, because of the existing relationship with one. Seems like a win:win for everyone.
Yes which is the definition of something that is very subjective. What you deem as "good value for the money" may be very different than mine...hence my comment.
