Hard to tell what you'd like, but going by your X-Men fandom.....
Teen Titans. I actually didn't start with this book until issue 6 (Aqualad's debut) but it's fairly solid and will probably feel familiar to you. Bunch of super kids trying to find their way, you know?
Aquaman. The book is big on politics, but the fantasy kind, not the "protesting in the streets because the POTUS is a moron" kind. Current arc is by Sejic, one of the industry's best artists. Lots of fun, great focus on Black Manta early on. Solidly consistent.
Super-Sons. Again, this should feel familiar for X-fans (depending on what X-books you read anyway). Robin and Superboy getting into adventures and trouble. Great art. Solid read. Not terribly serious.
Green Arrow. The book's about as subtle as a sledge hammer to the face. But its fun anyway and it's big on social issues.
Supergirl. A teenaged alien working with a shady government organization and dealing with some family drama crazy enough to make Magneto look like a good father.
Detective Comics. Batman and many of his partners from around Gotham deal with some crazy threats to their city. Damn fine book.
Mister Miracle. Only two issues are out from this twelve issue series, but if you don't like this....I dunno what to tell you. You're not human, I guess.
Superman. While some arcs get into the kind of big scope, epic adventures you'd expect from Superman, generally this book explores the new family dynamic of Superman and his wife and son. The book's quality has dropped a bit in recent issues but generally is a very strong title many considered among the best of DC's Rebirth launch.
Deathstroke. Hard to describe this one. One part family drama, one part paramilitary covert ops assassinations, one part superheroics. Damn smart book, solid art, and if you want a title that doesn't just do the standard superhero stuff check it out.
