I have always enjoyed flying on East Airbus aircraft. I had the opportunity to fly on an HP Airbus and connect to a US Airbus, and I could tell the difference!!
Too bad we can't keep the East configs... i mean, WN gives their passengers like a 33 inch seat pitch.. and we'll be at 31!
YES, HP (and now US) are the most uncomfortable flights. I know when their is a RJ or a 737 on a routing, I switch to TED/UA ONT-DEN-XXX So then I am in Economy Plus.. and enjoy the leg room. I much more care about pitch. That is why I do not fly some routes on HP/US... the alliance is a good option for now, since UA has the same benefits for a CP (if they are not upgrading)... I actually had more room to work on some UA Ted flights vs HP 737 in F... Row 2 has now workable room when that Row 1 seat comes back. HP is NOT Business friendly.. and we adjust to other airlines when needed... especially on last minute fares, they go to UA or others.
