I don't know what caused the fact that we have two multiverse movies in theatres at the same time. Coincidentally both tell a story about a mother's relationship with her family. Everything Everywhere All At Once is my favourite though. It takes the multiverse concept to the next level, while it also tells a very human story. Doctor Strange is nice, albeit a bit more formulaic. Still one of the better Marvel movies. Everything Everywhere is super creative, crazy fun and comes highly recommended.
