DCU feels BIGGER, the New Gods and GLC are awesome, and they have a lot of really great cosmic baddies. Marvel has fewer things to distinguish its cosmic scene, but I like those individual elements more than pretty much anything in DCU: Galactus and his heralds, and the Celestials.
DC: GLC- I've really taken a liking to the entire GL Universe . I love the idea of using emotional spectrum to harness energy as a power source. Yes, even all the other colored emotions.
Marvel: Surfer/Thanos/Ronan/Nova related stuff. I also enjoy the X-Men Shiar Empire storylines.
Asgardians, pretty easily. Surfer and some others are pretty great too. Thanos is by far my favorite cosmic villain.
Green lantern corps would be my favorite DC group.
