I actually feel Persona 5's OST is one of the better ones Shoji Meguro has done for the series, course I'm bias because I actually preferred the OSTs of P1 and 2 over Meguro's more pop albums for 3 and 4. The fact he did more of a jazz piece with 5 brought back some nice memories of his work on the Raido titles. Frankly, Meguro's best musical work has always been the ones for the SMT series like SMT III, Strange Journey, and SMT IV.

As for VI, I still consider it Uematsu's best musical score in both an emotional and technical level. Not saying that's for everyone of course, so I won't begrudge anyone who feels it fell short. I'm with Fynn that Uematsu's peak was certainly the FFV-VII OSTs, with a final hooray with IX's score which is a bit underrated in comparison to VI and VII.
