I used to have Priority Pass as a perk of a corporate card. I was unimpressed with the priority pass lounge in SJC. Filthy, bad food, mediocre service. Far worse than Centurion and Delta lounges.
Their lounges in other aiports seemed to be closed whenever I was in need of them.
Based on that, when we switched to a different corp card, I did not try to get a personal card w/Priority pass access (nor did I buy my own membership).
