Outlandos d'amour and Reggatta de blanc (odd album titles, by the way ) were pretty similar, but Zenyattà Mondatta already showed some unexpected electro-synth textures, and Ghost in the machine and Synchronicity(which sounds like a Sting solo album with Stewart and Andy as collaborators) were both very experimental and sophisticated.
So, you can appreciate a clear evolution between Can't stand losing you and Wrapped around your finger, or Message in a bottle and King of Pain, etc.

Anyway, ALL the Police albums have filler here and there

I love the police. I always thought the broke up at the perfect time. 5 albums with not many bad tracks, and many brilliant tracks. Since Sting was becoming more dominant, the music just would have languished into the stuff that Sting did as a solo artist.

I like all the singles, but several album tracks are my favorites. Just a few:

1. Deathwish
2. Driven to Tears
3. When the World Is Running Down ...
4. Miss Gradenko
5. Demolition Man
6. Tea in the Sahara
7. Masoko Tanga
8. The Bed's Too Big Without You
9. Bombs Away
10. Secret Journey
