Are Centurion lounges not worth it anymore?

I was thinking of applying for Amex Plat but I researched this and other subs i.e. r/amex and /r/amexcanada and it seems nowadays Centurion lounges are overcrowded and not so clean. Furthermore, some reported having to be on a waitlist to enter and couldn't use it. If the major reason I want to get the card is to have the loung access, it seems it's not at all worth the high fees. How has your recent experience been with Centurion lounges and other 3rd party lounges (not priority pass) in the past 1-2 years?
