If you want Priority Pass, you may be better off getting a Credit Card that comes with Priority Pass such as the Chase Sapphire Reserve or American Express Platinum, among some other CC's on the market that have PP as a benefit.

Some clubs you can access via Priority Pass are decent while some are mediocre to poor so it may depend on where you're flying out of and through and which version of Priority Pass you get. I've found outside of the US there are some decent lounges available via Priority Pass. If you get the one that gives you dining credit at various airport restaurants, that can be a decent value. My favorite Priority Pass Lounge option is the PGA Lounge at MSP, where you can use the credit given on entry on the golf simulators. Hoping to get in 9 or 18 holes on my layover at MSP this coming week.
