As a universe, I think Marvel is more intriguing. But DC has way better “individual stories” that work out of continuity because their characters are seemingly more iconic, kinda like Greek Myth. Marvel is more focused on soap opera drama and I think is more fun week to week but every story that’s ever blown me away was DC.
When it comes to animated series DC has the better ones, and I like their characters better too. However, Marvel has the better live action films for sure. I still need to catch up on a lot of them still though. ^_^;
I'd have to say they're both good in their own right. I like both. I deeply enjoyed Christian Bale and Michael Keaton's Batman movies and also I love the MCU movies and collect those.
