I'm digging Solo, but I also loved Rogue One. I haven't been into either of Williams' scores as a whole, but I'll admit that Rey's theme is one of the strongest in the series.
And I did love the work that Kiner did on Rebels.
So...
Rogue One Solo Rebels The Force Awakens The Last Jedi
1) Solo 2) Force Awakens 3) Rogue One 4) Last Jedi
Solo is the most exciting and rarely gets boring (don't have to skip many tracks). Can't stop humming the theme. Rey's theme is pretty amazing too. One of the best in the series. Everything about the Last Jedi turned me off (music, writing, acting, etc.)
