I do agree about BA F being better especially for LH.
I'd take a PJ for shorthaul though as the time on the ground at each end will be a much larger % of the end to end journey time when flying commerical and it's a whole lot more hassle.
The one thing I loved on my first PJ trip was being met in the airport (BRE) by the pilot who greeted us with "I'm your captain, when would you like to take off?"
