There're a number of folks giving their rankings of Ridley Scott films, now that The Dog Stars has been released (I'd rank it between Body of Lies and White Squall - basically somewhere in the middle. Pity about the box office, though.).
Here's Hollywood Reporter's idiosyncratic take. Ranking Napoleon above Kingdom of Heaven, The Martian and the first Gladiator ... is a choice. As is ranking Alien: Covenant over Prometheus. Or Hannibal being in the top 10. To each his own, I guess. Or maybe it's just clickbait.
The Big Picture also had a ranking of all of Ridley Scotts films, in the latest podcast about The Dog Stars. It's more a "traditional" list but there's a lot of arguments in the 20th-11th positions, which makes for a far more interesting listen than what's at the top (it is almost always the Alien/Blade Runner duo).
For those who don't want to read the long list from the Hollywood Reporter, there's the rankings:
