Honestly, I'm much in the same boat. I've always been Marvel over DC, and really can only get into DC a lot by animation. I can just jump into Marvel much easier than I can DC, because regardless of what book I'm reading it feels like it's part of a natural and connected world. My enjoyment of DC is rather limited because it feels like a bunch of micro-settings that only occasionally interact with each other. The main ones I like to read are Batman and related titles, Teen Titans, Green Arrow and Deathstroke. A little bit of Wonder Woman as well. With Marvel, it's a lot more varied. I'm currently reading all the Spider-titles, X-Men, Runaways, Daredevil, Avengers, and some individual Avenger stuff (including the IM/Cap/Thor trinity), and the Fantastic Four, and I know there's more on the way.
Also, I know it sounds odd to say, but I
really like the way few Marvel heroes can just fly as a superpower. Stan Lee said he hated how superheroes can fly for no reason, and set out to make sure everyone had some kind of unique mode of travel. It really does make characters feel unique, whether they hold a super hammer, use jet propulsion, swing on a web, have a suit of armor, ride on an object, glide in combination with sonic powers, leap great distances, have a wingsuit, a magical artifact, or by surrounding themselves with energy. Compare this to half the DC heroes flying just 'cause, or in the case of the Flash, running.
