I'm glad to meet another Steph fan!! I love the old Titans comics, but I'm biased towards that era because it's simultaneously campy and heavy (like, the omniscient narrator is still a thing but the stories can get pretty dark) and I love the art. What little I've read of New 52 Steph has disappointed me because I feel like they made her too dark and took away her fun side? (which is my biggest complaint about New 52 in general--not everyone has to be Batman!) and as far as I can tell her relationship with Cass isn't what it used to be, which makes me sad.
