Ranking these movies is not as easy as it may sound, and yes I know MoM was divisive and LaT was mostly hated on by the internet, but I guess my standards are pretty low as I love the former and enjoy the latter a lot, and I found WF to be beautiful and moving. And I love how different they feel even if you can tell it's the Marvel sandbox they are set in.
So we have three wildly different movies tackling different tones and sub-genres within the confines of superhero stories, two of which had a lot of problems during production. We go from the spooky, horror-lite Doctor Strange to the Rom-com Thor to the somber, serious Black Panther and you can clearly see the hands of Raimi, Waititi and Coogler bringing different styles and moods into the classic Marvel template, which I agree some people appreciate and some don't. You may love Raimi's style and hate Waititi's and viceversa and that ultimately shapes your judgement of the movies.
I think, coming from a place of genuinely loving these characters from the comics, I'm just happy to see Scarlet Witch, Mighty Thor, Gorr, Namor (I think all three movies nailed the villains!) etc on the big screen, while continuing the arcs of the main characters in cool and sometimes unexpected ways. I know Phase 4 has been rough for a lot of MCU fans while haters have been feasting since Eternals got its Rotten rating, but I just loved it all. So my ranking at the moment is
Multiverse of Madness
Wakanda Forever (pending a rewatch)
Love and Thunder
