lounges= priority pass

i am about to start doing a fair bit of travelling , mainly between MCO and LGW with the odd LHR and JFK. as I will be using miles and flying PE getting to use the VS lounges is unlikely.
SO my question is- is priority pass worthwhile buying and what are the lounges like
Gatwick - the servisairs = or the Sofitel on arrival has showers which would be handy
Orlando- the united red carpet
JFK Swiss lounge
any thoughts/advice appreciated
